Uprated charge cooler kit for Audi A4 B8 and Audi A5 8T 2.7 TDI and 3.0 TDI

Give your V6 diesel the cooling headroom it deserves with this UK engineered AIRTEC upgrade. Designed as a genuine plug and play solution, it sits neatly behind the factory bumper with no trimming, no drilling and no changes to the crash bar. Expect lower charge temps, stronger mid‑range punch and repeatable performance on spirited road use, motorway runs and remapped setups. We have fitted this kit for customers and on our own cars and the feedback has been excellent for reliability, consistency and value.
