You need this extra to make it last:

In stage 2, we recommend installing NGK RACE spark plugs. This means you always have a stable spark and don't have to worry about misfiring. To ensure that your engine oil does not overheat and that your engine always has an optimum temperature and oil condition, you absolutely need our oil cooler kit!

BAR-TEK® TIP!

Here 102 octane fuel is mandatory. Always check the diverter valve! The membrane is often cracked, which causes you a high loss of power. The V-Max is always suspended with our tuning! Here we always recommend a catchtank kit for engine and transmission.

Cooling Guide

Consistent Performance More Room for Overclocking Longer Lifespan

You need this for optimum cooling:

If you want to get the full performance out of your 2.5L TFSI, you must not forget the cooling. Even a little extra power puts a lot of strain on your engine! The thermal load increases and affects all areas of your vehicle, even the transmission suffers from the new power. At best, the hard-earned power is reduced again; at worst, your engine suffers major damage. So that you can tune your engine safely and reliably, we provide you with everything you need for perfect cooling. Although it is ideal to install all parts together in a cooling bundle, you don't necessarily have to order everything at once. Each product helps you to improve cooling.

White Audi RS3 (8V) in the rain

After a long search, I finally found the tuner I trust. I spent a lot of money before and never really got what I wanted. My car has been to Bartek twice so far and I am more than satisfied 🔥 it feels like a new car. Customer friendliness is very important here and I think the best thing is that the boss never leaves just one question unanswered.

For me, 1 time bartek always bartek.

Time for the next Upgrade!

Nach 3 Jahren & insgesamt 30.000 km mit dem Thor G35-1050 – daily mit ~700 PS & 2.0 bar und mit 2.6–3.0 bar im Rennbetrieb – ist es Zeit für das nächste Level!

Der Turbo hat alles ohne Ausfälle gemeistert. Jetzt geht’s mit neuen Upgrades weiter – mehr Performance, mehr Erfahrung, mehr Boost!

Hi!

I just wanted to say thank you. I've been driving the RS3 a bit over the last few days and it's exactly what I wanted. It runs great. Perfect torque across the entire rev range (for me). And the transmission is better too, or rather, the problem is gone.

Thank you.
