Best Audi A3 Mods (and ones to Avoid!) [8L 8P & 8V Tuning Guide]

Discover the best mods and tuning upgrades for your Audi A3.

We look at engine mods and list the best mods, you'll learn the best engines for your A3 if you were buying one and we also cover handling mods.

From engine mods we look at A3 induction kits and if these are worth fitting, and discuss remapping your engine and the turbo upgrade options out there for you.

I also look at the effects of larger allow wheels and how they affect performance on the A3.

This tuning guide has been designed to cover ALL Audi A3 models over the years, and we have some more detailed guides coming up soon for each model and engine so we've got you covered when it comes to upgrades for your A3 engines.

Rather than just provide a list of mods, I explain the best mods. Why these mods will or will not work well on your A3. I also show the most effective Audi A3 mods for your money to ensure you get the best performance possible.

I owned an Audi A3 8L 8P & 8V versions, and I've had the 1.9TDi 1.8T 1.4 TFSi 1.5 TFSi and 2.0 TDi, all are great engines and I've found some great mods that work well, and some to be avoided.

The V6 and 2.0 TFsi are worthy of mention, as when modded they become quite potent track day cars.

Absolutely love your content!!! I have just bought a 2006 A3 Sportback 2.0 TDi (BKD - 140hp) which I am planning to strip down completely and rebuild and modify both mechanically and cosmetically along the way. They are such fantastic vehicles with so many options for modification. Really looking forwards to your future videos on the 2.0 TDi. Keep up the amazing work.

My husband bought an a3 s line 2.0tdi 140hp had limp mode issues but now all sorted, it’s now running hybrid turbo stage 2 remap with 3inch exhaust updated injectors and s3 intercooler stage 1 clutch and induction kit so much fun does puff a bit of black smoke on full throttle but no rolling coal

I have a 2008 8P type quattro 3.2 vr6. Tuned to about 265-270 on 93 octane. As for mods. a dogbone insert, 24mm rear sway, S3 front arm rear mounts, ECS tuning intake tube, an ITG drop in filter, DSG alloy filter housing and Powerflex front sway bar insulators. Running the new Falken Aklimates now but haven't had them long enough for any opinions. Prior to that I've run Sumitomo HTR P02 in front and P03 in the rear. They have worn well and the P03 have worn better than the prior model P02. Both grip well dry or wet, wear nicely and stop better on snow/ice than many all-seasons. I ran Sumitomo Ice Edge full snows without studs on extra wheels for a few years and the last two years since they weren't good enough for a bad winter so I used them for 12k miles all year round and they wore surprisingly well and even. All the wheels are factory 5 spoke alloy 17".

[Slimcone]

I have a 2015 a3 2.0 TDI, it’s all stock, my emissions warranty expired so I’m. Looking at modding it now

[petermcgimpsey]

I recently have bought a 2018 Audi a3 1.6 as hatchback! Purchased a honeycomb grill and Maxton splitter to go on it😁 What would you recommend for performance upgrades and for the sound of the car?

[johnnyberglund]

I have a 2006 2.0 l fsi, quattro, 147kw.
Not much work, just standard job and service.
Change back springs this winter, car feels almost new to drive, fast also!

I have a 1.4tfsi 8v pfl, no remaps/mods done so far. I just want the exhaust a lil louder than it is, will you advice catback or muffler delete?

[danielabarjel]

I have a 2015 A3 1.8t FWD, so far I have ecs intake, muffler delete, resonator delete, and need advice on mods. Tires spin a bunch so looking at a dogbone insert.

[JonathanPicardi]

Just subscribed and so glad to have come across your channel, awesome content

[markblackman]

brilliant video, i have an Audi S3 8P, 2010 in sprint blue, with a K&N washable filter, it breaths harder at high rpm, otherwise its stock 265 bhp, i feel its quick enough without a stage 1 remap, but i will be fitting a turbo delete muffler kit later and may look again at soft poly bushes £300, the brakes are really good, may replace the the rear calipers, and rear shocks, carry on with the great work and knowledge you share !

[sonsofsupernova]

Amazing video. Great information mate. Greatly appreciated.

[FailedEmmisions]

I use ebc yellow stuff for the front and they're more designed for street and track use, a little dusty but they have great stopping power. I use red in the rear which is high preforamance street pads but not quite as aggressive as yellow. Great dust management and still really good stopping power. You should try ebc again on your next set of pads. I love mine and the yellows have been on for about 20k miles and still have atleast 10k more miles left if not more
