A silicone throttle body boot for the Audi 2.7T that fits great and won't rip like the factory TBB. Stop worrying about harmful boost leaks, with 4.25mm wall thickness the Achtuning TBB will last the life of your engine. The Achtuning Throttle Body Boot includes 3 constant tension spring loaded clamps and 1 OEM style pinch clamp for the boost sensor.

Our new Version 2 TBB is an injection molded reinforced silicone boot that looks almost exactly like the OEM boot, this allows a stealthy install while giving you a perfect fitment. Unlike the competition, the Achtuning TBB still allows fitment of the boost sensor clamp and does not interfere with fitment of the front engine cover.

This kit fits all the Audi 2.7t engines, B5 S4, C5 A6, and allroad.
