CTS Turbo Audi 2.7T Throttle Body Boot

The CTS Turbo throttle body boot replaces the factory rubber connection on Audi 2.7T biturbo engines, addressing a common failure point that causes vacuum leaks and drivability issues. Constructed from reinforced silicone, this boot maintains proper sealing between the throttle body and intake manifold under heat and pressure cycling. Designed specifically for B5 S4, C5 A6 and C5 Allroad applications from 1998 to 2004, it eliminates the cracking and deterioration typical of original equipment. Direct replacement installation ensures reliable air metering and consistent throttle response for tuned and standard 2.7T engines alike.
