Stupid tuning modifications that actually make your car WORSE!
We all know a lot of people like to modify their cars, and most of the time, they do it to improve performance or to add their own personal touch to their car. But at the same time, there are some modified cars out there that either look absolutely ridiculous and can be down-right dangerous! But what are they? Well, wonder no more! We’ve pulled together our list of the 11 most pointless mods out there! But are you guilty of any of these? Or do you disagree with something we’ve added to our list?

Adding an M or AMG badge increases performance by 450hp, everyone knows this.
as an M owner , i feel proud whenever revving the engine infront of them quite ‘M’

Basically, established car manufacturers know more about building / improving cars than your average human. Priceless information. Thanks for sharing, Mat.
I think of this every time I see an 18 year old kid with a “hot” Honda Civic.
I hope you were being sarcastic
@@MrRea112 car manufacturers probably do know more than someone whos designing an aftermarket part, issue is higher ups tell them to make cars with lower costs, greater wider appeal and greater ease of production and thus are compromised in one aspect or another (in 99.9% of cases). its crazy how people like OP think just because manufacturers throw millions at R&D means youre getting the best performing product possible with no room for improvement
@@RogueCowTurd True. Doesn’t that cynicism make it even more outrageous? The customer is treated like mindless fodder to be fed the cheapest muck at the highest price. There was a time when companies like Mercedes possibly Toyota genuinely believed the customer deserved quality, reliability served with integrity
@@MrRea112 in some cases yeah for sure, minimum viable product is definitely a thing but at the same time regular car brands cant be going out and putting the best performance parts they can design on their production sports cars. for example toyota/bmw cant slap the best flowing titanium exhausts on the supra because any excess cost needs to be passed onto the customer which can make the car uncompetitive financially, they also have to deal with many countries laws so a loud exhaust with no cats will stop it from being able to be sold in some parts of the world and even if we ignore that, the general person who just wants a sporty car doesnt want endless drone at highway speeds and their rear bumper covered in soot all the time. these are the types of things a manufacturer needs to factor in when spending millions on R&D. the aftermarket however does not. the people who buy exhaust kits dont mind that theyre going to be louder or more expensive to produce (to an extent), brands dont need to worry about laws since they advertise everything as "not for street use".

@Itz bubz Look at my comment
Interior strip, light weight racing seats, and a roll cage are the way forward if you want instant noticeable gains in acceleration and handling. I've not gone the whole 9 yards yet, however, many moons ago I did have a Corsa mk2 1.2i 16v 3 door gutless piece of shit which was totally transformed by removing all the carpet, roof lining, insulation, rear seats, and any unnecessary plastics. All that was left was the dash, front seats, and door panels. I then upgraded the front discs, pads upgraded all round, and put on 17inch rims. I think the tire size was 195/45/17 which were wider and lower profile than standard. What a different it made! First thing I notice was the grip. Because I was use to the handling characteristics of the standard set up I'd find myself turning in too early on corners expecting the car to slide. Scandinavian flick became unnecessary on way tighter corners than before hand. Handling, acceleration, and braking was also significantly improved by the wheel's and weight loss. In a straight line I was obviously getting left for dead by larger engine capacity cars, but on the twisty, bendy UK A and B roads it came to life. It was like driving a Go-kart! Many a 3 series BMW had been left for dead in my rear view on country lanes.
If you remove a car's engine it saves a lot of weight therefore it is faster!

Oiled air filters are a great idea with a carbureted engine, but as stated here, not so much with electronic induction systems. A favorite mod to save fuel at one time was to jack the back of the car up so you're always driving downhill.
Haha not sure if this a joke, but drag racers lift the rear so the car squats and puts power down better when racing. This is of course coupled with a softer rear suspension and stiffer front.

Great video. This video should be mandatory part of classes when youre going for your driving license. Its well presented and not boring. And covers the most common blunders :)
Negative camber on street cars is the dumbest thing I’ve ever seen. It looks horrendous and it ruins your car. Bravo.
I thought underside neon lights were the dumbest thing that could be done to a car until I saw what people do with the camber of their car's wheels...
I have no idea who ever thought it would be a good idea to do that
Japanese do it to stand out, not necessarily to look good.
in shitty road... it do help since inside tires.. are harder than outside in sport car... and if the road is wavly... the tires still hold on something and traction control do had the car going stringht.. i had the road right in front of my house and i had 2 sports car... normal setting.. it alway pushing me to the side but the negative one don't...
I like the looks of it so it isn't stupid

Stripes mate u need stripes

Those camber maniacs... that's one of the most hilarious things I've seen in a while. :D
Yep. Apart from the harmful performance handling effects, that one mod doesn't even make the car look any better, very very very much on the contrary!
People think it looks good too thats the worst part

@@viku4 well they can, but they are not allowed to. greed governed planned obsolesence
well, said "engineers" have fucked up their fair share as well (recalls anyone???) I applaud anyone who "garage/front yard built" an amazing machine that works.
I see your point. And it's true there are kids out there who only want to be seen (and heard). Big shiny rims that cost more then the rest of the car. A loud "sporty" cat-back exhaust that does nothing but making noise. Cars lowered to a point that they need to step out of the car and push it over a bump. But there are also drivers who want their engine run more efficient. To have better handling. And there are professionals, engineers with master degrees, working for companies who have also spent fortunes on design and engineering to deliver just that. Some premium car brands even have "in house" tuners or at least approved tuners because they know those tuners have the know-how to safely increase performance. And there a lot of reasons car manufacturers don't do it straight away. Cost savings are a big one but also because the opposite of what you say. "so that this machine works perfectly under its specified conditions." They don't want it to run perfectly under specified conditions; they want it to run under ALL conditions. From the sahara to siberia. Or from the salt lake plains to high up northern Canada. With regulated high quality fuel but also with some mixture some guy sells in buckets on the side of an African road. Grandma is allowed to torture the clutch and some clueless guy can press the pedal to the metal with a cold engine. It's a whole different story if you can narrow down the parameters. If you know you will always take quality high octane fuel and you live in a region where it rarely gets over 35° or under minus 15°, you don't need that big safety margin.

well, if it is a track car it might give those rear tyres some grip and temperature. But that is a massive might
Surely you can't really spoil a Pugly! Says the person with a Fiat Doblo as family car. Which for reasons I cannot fathom came from the factory with a spoiler, because a 95 hp van with seats managing an impressive 0-60 in just over 14 seconds, needs that like, well like a Peugeot needs a giant spoiler. I have done well in the Doblo, so far I haven't been overtaken by anyone using a zimmer frame, it was close but I won.
I saw a Peugeot 107 with about 6-8 visual mods done to it. Hilarious to look at, performance wise still a 107...

Spark plugs are also temperature rated. Therefore on a modified engine (cam, ECU tune, bigger injectors etc) will benefit from a cooler rating. Stock spark plugs will cause a loss of performance, increased cylinger temperatures and therefore the risk of detonation, pre igntion and melting the pistons. Running cool plugs on a stock runs the risk of inefficient fuel burn, fouling and piston damage.
most these mods increase your car's .. unreliability
I was thinking the same thing. Depending on application you’re going to want hotter or colder plugs. As an example a boosted car will benefit from cooler plugs because of the increase of intake temperature you’ll have a much more safe burn where if you had hotter plugs you risk predetonation
As mentioned plugs depend on application. In a boosted car It’s a good idea to use 98 Ron or higher. For the same reasons, reduced chance of detonation, melted pistons etc. I don’t use anything but 98 Ron in my G40, the supplementary manual recommended 95 RON. What was the standard fuel grade in 1990? It also suffers the cost of platinum Bosch W5DP0 plugs which were specified with the Bosch digifant engine management. These were OEM on Porsche 911 turbo’s and Ferrari’s of similar era, hence the cost of £20 per plug! Associated rich-boy tax slapped on there by Bosch.
@@MikeBarbarossa if it is tuned properly with supporting mods and taken care of i think youll find FBO cars have pretty good reliability, anyway stock is boring
You are so right sir. Iridium or Platinum is mainly used for petrol cars. For LPG cars you need sparks with a higher heat degree so in most cases they use sparks with nickel plated copper elektrodes. So it depends on the type of fuel witch sparks you need. There is also a difference in quality. The higher quality sparks last longer and perform better. In the near future sparks will be operated at very high frequenties witch improves the spark and live span even if they are operated at very low temperatures.
Summary: if you are going to mod the engine, tune the ECU accordingly
Yes, its the best primary upgrade tho it can be quite expensive for certain cars
You could also purchase the tuning software and do it yourself. It's cheaper, but takes more research. It's not dangerous, provided you don't crank the boost up on your 1.2 turbo corsa all the way up to 60 psi thinking it's a GTR 😂. But it does offset that cheapness with time invested into learning and doing it properly. So it's what do you value most. Money or time.
@@annahenrietta9517 that only will work for someone with good technical knowledge. Ability to read min/max settings for engine isn't giving you full proper rundown on how it's going to affect engine and performance in any term. To suggest it to do to someone who can change couple filters and change tires is plain silly
Keira Metz or don’t. Get a proper tune by a company which has a good reputation tuning that particular engines and most importantly a DYNO
@Keira Metz i do agree with that even though it would take a lot of practice and reaserch but if u learn how to do it u can save a lot of money on future mods and actually get to learn something

Excellent video! Can personally attest to a few of these, I realized my car (tuned f22 230I) handles significantly better on a smaller than stock wheels with a taller sidewall. Especially with slightly deflated (3-5psi) semi-slicks in the rear, and oem spec tires in the front, it can outperform cars with quite a bit more hp just from the better weight transfer and less inhibited acceleration. Would love to see more vids like this, and think it would be awesome if you guys made some tuning/modding suggestion or alternative vids.
One other thing about cone filters - first check where the stock airbox is pulling air from before you attempt to "improve" it, or else you might just be replacing your stock cold-air intake with a hot-air intake. A lot of cars already pull air from outside the vehicle- such as behind the headlight housing - even if you install your cone filter properly, it's still going to pull in warmer air than the stock intake does.

@@tigerpjm no body Cares to know 💀
@@MR_stone69 The c**t that deleted his comment cared.
Case in point. One of my first cars was a Hillman Imp. I tweaked it from it's standard 39bhp to 118bhp. I put 3 degrees of negative camber in the front to eliminate the horrific understeer of the standard car (rear engine, standard setup removes tendency to oversteer by using lots of positive camber on the front. That worked pretty well, though it was a bit prone to snap oversteer on the limit. The high lift cams that were needed back then to get 118bhp from a 998cc NA engine were less successful and removed all of the minimal torque that it had as standard - it needed close to 4000 rpm to pull away on the flat, and more like 6000 rpm to pull away up any sort of a gradient. Being in an uphill traffic jam was frankly embarrassing. Retaining the standard drum brakes wasn't a great idea either - a hard stop from 80mph+ meant that the bakes completely gave out at about 20-30mph and you went sailing past your intended stopping point. Hopefully there was nothing in the way. Fuel economy was appalling. The standard car did 50+ mpg, after mods, it did 25mpg if I was careful, but 8mpg when it was driven hard - not great for a 998cc engine. But hey, it was a lot more entertaining than a standard Imp, and I was a student :-)
Outrageous!! I'm so old I used to think they were cool.
Exactly, 3 degrees of camber and a whole load of detailed engine mods gave you a result. 30 degrees and an plug in LED does nothing good.
Best mod that works and is cost effective are high quality performance tyres
Driver training is the best mod.

The performance air filters don’t filter as well either.
that is true , actually i removed my air filter in the car and it accelerated quicker , then i put sports air filter and it had the same effect as no filter .. i always come and check up the air filter box just in case i need to clean it , worked fine for the past 2 years , no problems whatsoever

I'd seen this and I was looking in the description for credit to you or at least on the image itself. Didn't see that. So I was sad.
The easiest and most noticeable performance mod you can do to your car is a nice set of tyres. You’d be surprised the difference between the usual all weather tyres and sport tyres make on any car, from a dinky Toyota Yaris to a powerful Ford Mustang.
I fitted a ring magnet around my fuel pipe and I got much more power and economy in my mind.

Not always. Modding your car is no different from modding yourself or what you have on/with you. Shoes; They do not always increase your 'performance' or comfort but guess what you buy them as you like them. Probably never curse your wife for those heels she looks so good in either right? Hair colour; How does that make you more efficient? Tattoos. WE, (not me as I don't have any of these on my cars), like what we like. EVERYTHING in life is a compromise. We give away some things with 'real' measurable value to get things that have value that is tangible to us as individuals.

Am sure others have covered this but the large spring clamps shown on this video are for temporarily compressing a spring to dismantle a combined damper and spring strut. Those used to clamp springs for driving are much smaller and as stated are a bad idea. Worse is cutting a spring to shorten it. Manufacturers spend millions on getting the suspension geometry just right as a useable compromise. Mess with it your peril as ride quality and handling dynamics will be altered. Great video BTW !

The differences are extremely minor in most of these cases, but it's very clearly there Because I drive that car all of the time. If you're paying attention to your car.

Well, I learned some things there that I never realised. This is why I subscribed to your channel. 👍👍👍
Higher octane helps if your car has a sensor to detect the octane rating. Mercedes Amg cars made for 98 octane but that is just for maximum performance they will detect 95 octane and tune down the boost. I am not sure but I think most performance cars with turbos does this.
That's true for any modern petrol car. It's a relatively cheap thing to do (simple sensor, the rest is software) and there a more benefits than just supporting different fuels. It allows the engine to run with smaller margins and also helps for other things which affect when knock might occur such as temperature, increasing average efficiency.
Even my non-turboed S2000 does that. It'll run happily on 95 RON, but is noticeably more responsive on 99.
BMW had that in every (non-Diesel) car in the mid-1990s (maybe earlier). The car's rated power and fuel consumption was for 95 octane. With 98 octane, performance would go up and fuel consumption would go down (but not enough to save you money as the 98 octane fuel is a bit more expensive). In the 1990s, there was also still 91 octane fuel. The BMWs could run on that, too, with less performance and a higher fuel consumption. 91 octane fuel is cheaper (but not enough to save you money as the fuel consumption goes up). 95 octane fuel would give you the best "mileage per dollar". Nowadays, you can get 102 octane fuel. For absolutely ridiculous prices. However, most cars will only recognize octane numbers up to 98, so 102 octane does not give and improved performance or fuel consumption over 98 octane.

The wheel spacers to bring your tires 4 feet out were my favorite. Then you can actually see your tires while you’re driving.
It makes your car an open-wheeler. And everybody knows that formulas are fast

Well put together, decent explanations, over your performance improved ! Ha ha ha
I still can't believe Matt missed putting a huge exhaust system on the back as one 😂
Replacing the back box or adding a 'sports exhaust'😂 is a quick way to reduce your car's power output - it detunes the gas flow which ultimately upsets combustion.
But that actually does increase performance, as does more exhaust pipes, eg: s3 has 4 so the co2 and other stuff can escape easier, that’s the basic explanation.
MiataBRG no it doesn’t, a sports exhaust is for mostly noise, as it has the valves for it. Doesn’t reduce anything

What if someone says installing spark plugs to a diesel increases power And the guy believes it
it works tho, when you start the engine it gives you 1000hp and 5000nm at idle
The lack of likes and comments on this reply makes me think people believe diesel engines actualy need sparkplugs.

@@lordrefrigeratorintercoole288 then those people didn't even understand the whole video in the first place
@@lordrefrigeratorintercoole288 They good thing of not needing spark plugs (AKA electricity) to run is that diesel engines can run without a battery, it happened to me a few times back in the days (of course you need to push to start it).
This is the best video I have ever seen regarding car mods. I hope everyone who is into cars watches this.
The octane booster does work in countries that receive low quality fuel, by bringing up the octane levels to what manufacturers actually expected the car to be using
i'm still over here laughing at the Coke and Mentos powered Honda
More like soda-and-candy-lubricated Civic
The vids are great keep up the good work, love watching the vids I even go back to rewatch them lol
Watching this had just saved me lots of money lol was going to decat my car love the advice
Don't carry a spare, that will make your car faster and safe some fuel. But don't get a flat or you won't go anywhere at all.
Asking Carwow to make a video on the facelifted 5 series and M5 attempt 2. I won’t stop.
Solid video. I like the fact that you mentioned that yes, you can do some of these mods, provided the mods you make work well together and the car is set up for them.
Added K&N air filter, added Eibach lowering spring kit (lowered 1&1/2 inches), switched out to double Iridium spark plugs, went from 16" all weather tires and wheels to 18" tires and wheels, and switch from regular 87 octane to 91 octane and the car performs and handles beautifully. Takeoff is super quick, and fuel efficiency has increased from18 mpg to 22 mpg.
No, it doesn't. It's placebo at best, unless you had it tuned as well (see 13:00). The "improved" fuel mileage you're seeing is diameter change from taller tires which alters gearing, which alters speedometer, hence false mileage of car. Did you even watch the vid? He actually explains why these things are bogus really well.
High octane fuel does improve power/efficiency if you car has variable valve timing and anti-knock sensors, and most modern cars do have them. I've seen dyno tests on my 20 year old E46 330'Ci that showed a 3% increase in performance/efficiency between 95 and 98 RON (they were done in Europe, so they didn't have any crappy 91 RON to test like we do here in Australia). So there's definitely no point increasing fuel grade beyond the manufacturer's recommended grade (which is the maximum the engine can take advantage of), but if the minimum grade and recommended grade are different (e.g 91 vs 98 in my case) then you'll get a difference moving between them. Your car is basically de-tuning itself when you use a lower than recommended grade... Also wheels are not just un-sprung mass, they're rotating mass as well, meaning they act as gyroscopes resisting changes in direction. Lower profile tyres don't just increase mass (even with the same total diameter, rubber is generally lighter than alloy, so more rim and less rubber means more weight), they move the mass further out from the center, which increases the gyro effect. There is a reason that race cars usually have high profile tyres - at least until recently where they're increasingly switching to lower profile to "make the cars look more like street cars for marketing purposes", invariably hurting lap times in the process.

The man has a Porsche. I believe he sad it at least 27 times.
And he said it WRONG every single time.
We won the war. He said it right.
Does he?? I must have dozed off 27 times. Curse this pesky narcolepsy

@@NaeMuckle yall won the war and havent done anything significantly ever since so shut up and say porsche correctly
I can agree with everything beside the fuel additive, I can clearly feel the power I get when I add it. In fact, the older the car, the more power it gets from my experience, I drove a Ford Focus 2006, with a 250mm fuel additive the car drove almost 8% faster, shifts where moving far more accurately and economy raised by about 5%. Its a fact, I've checked it out quite few times. However worth noting, that even when economy raise by 5%, the costs still ending up higher per km than actually driving less without paying for the additive which end up costing more. I call it lifestyle, if you cant get your sport car, that's the next best thing.
Very good technical education video. Much better than some car reviews!
Congratulations, one of the best Carwow videos !! We want more like this.
It's stupid that there is 171 comments and 161 are saying 'I am first'...

Weight reduction (on an '80's Firebird) - - Remove carpet padding and insulation that's behind interior panels. Remove front bumper from behind bumper skin. Remove door crash beams. Remove whole Air Conditioner system. Re-locate battery to right rear fender (weight bias is like moving the engine back 10 inches) Car is noticeably lighter and steers quicker.
Loved your video bro definitely helpful!
Car manufacturers have different width wheels on stock models. I.e. the offset is different. You can add spacers to some degree and stay without the optimal performance range. Think about it.
Humble brag... “like my Porsche” bless
which looks like shit

Love your chanel. Do next "How to stay away from bad mechanics"😁
Thanks for the upload, great content.
Theres so many half-truths in there. Alot of these are very valid mods under the right circumstances.
Which in those cases, he added context to it. Like some CAI's AFTER a tune. "Performance chips" vs getting an ECU tuned professionally, negative camber for track usage etc
@@junkiexl86 I have seen CAI to increase power almost 12whp on C6 Z06 without a tune. Depending on car you may gain alot more than 1-2hp.
@@DuBstep115 Alright, lets do the math. A CAI is maybe going to get you a 2% increase in power, so if your car is typically around 170 hp, thats a little over 3hp on a good day. 2% on a 505hp engine is, lemme pull out my Casio fx-115ES, hmmm, 10.1hp. So yeah depending on your car's hp output yes you will gain hp, but again, it's only about 2%.
@@Jimhbs85ohyeah 12whp is almost 15hp and 15 from 505 is ~3%. Huge gains for high performance NA car for almost no cost.
I agree. Its sort of making out that factory car setups cant be improoved on by the diy tuner. I go the the Nurburgring quite a bit and while some cars are set up by companies, most are done by diy'ers . I do agree with some of what he said though...tbh, if the mod is done badly, EVERY mod is poitless/dangerous
At 13:17 I laughed out loud. That made my day. What is the name of that KZhead video with the excessive number of spacers?
Whistling Diesel
Great Information. What I would like to know more about is, with most manufacturers “everyday” cars, they come in varying specs of engine performance (and naturally you pay a bit more). But is there much more to the gains, or is it generally a different mapping? For instance, in VAG engines, there is X amount of 2.0 TDI PD/CR engines.
Every single time he says "more power", my inner James shout "BABE!!!"

wings, non-standalone-ecu tunes, higher octane fuel, decats etc can all work, you've mixed wheel sizes and tire width a little as well. What you've done is mostly covered mods that might not work, and entirely aestethic mods. You've also ignored that cars are engineered to compromise between a lot of things, and hence shifting the compromise toward performance can be valid. So the engineer excuse doesn't work
This was one of the best videos I've seen from you.
