Audi TTS (Mk3) engine tuning & performance parts
R44 Performance stocks 10 engine performance parts for the 2015–2023 Audi TTS (Mk3). Parts include heat management, intakes & air filters and oil coolers & radiators, from brands including MOTUL, Funk Motorsport, CSF, MST.
Most builds follow the same order: an ECU tune first, then intake and cooling upgrades such as intakes, charge pipes and intercoolers to keep temperatures in check, then fuelling, turbo and internal upgrades for bigger power targets. Each step supports the next, so it pays to plan your build as a whole.
Results depend on the combination of parts and the tune that supports them, so speak to our team before you buy. We can recommend a proven setup for your TTS (Mk3), fit it at R44 HQ in Wembley, and deliver across the UK and worldwide.
