034Motorsport Turbo Inlet Hose, High Flow Silicone, C4 Audi S4/S6, AAN Black - 034-145-A005-BLK
This high-flow silicone turbo inlet hose is a direct-fit replacement for the factory rubber inlet boot on the C4 Audi S4 and S6, and it also suits K24, K26 and RS2 turbochargers and most turbos with a compressor inlet of about 2.25 in. 034Motorsport explains that the unreinforced factory boot can collapse under the turbo's suction once boost is raised, and it commonly cracks and leaks, which upsets MAF readings. This hose is made from automotive-grade silicone with four layers of reinforced nylon to resist collapsing, and its smooth, non-corrugated bore flows more air than the factory part for better throttle response. New hose clamps are included, and the hose can be used on 3B engines with some modification because the N75 and bypass valve locations differ.
