Audi TT Mk2 (8J) Tuning & Performance Parts

Audi TT Mk2 mods span a wide engine lineup, from the 1.8 and 2.0 TFSI through to the 2.0 TDI, 3.2 V6 and the TTS. Awesome GTI stocks Audi TT Mk2 parts covering engine tuning, braking and styling for the 8J, and what suits your car depends a lot on which of those engines you've got.

Engine Tuning for the 2.0T

RacingLine builds a performance intercooler specifically for the older 2.0T EA113 and EA888 Gen1 engines, addressing the point where the factory unit starts to hold power back once things heat up. Their  diverter valve upgrade covers the EA113 and earlier EA888 engines found across the Mk2 TT range, and replaces the factory unit with a billet aluminium piston design built to respond faster under boost.

The TTRS is also well known for suffering from heat soak, particularly once power is increased, so an uprated intercooler is a worthwhile supporting modification. Wagner Tuning and Airtec both offer performance intercooler solutions for the platform, helping keep intake temperatures under control and performance more consistent during repeated hard use.

Braking for the TTS and TT RS

VBT's Road Plus pads are built specifically for the TTRS 8J's Brembo calipers, giving a proper day to day pad that still copes with light track use once bedded in. It's worth matching your pad choice to your exact calliper setup on this generation, since the TTS and TT RS run different brake hardware to the standard TT.

Audi TT Mk2 Upgrades for Wheels and Everyday Extras

034Motorsport's ZTF-01 forged wheels are a real step up for anyone wanting to reduce unsprung weight rather than just change the look. A strut bar and cargo net kit is a neat upgrade for the Mk2 TT, combining added chassis bracing from the strut bar with a more finished look and useful boot practicality from the cargo net..

Anti roll bars and air ride are both available, giving a choice between sharper handling and a fully adjustable stance depending on what you're after.
