A silicone throttle body hose has been developed by Mishimoto for the Audi S4 from 2000 to 2002.
The Audi S4 Silicone Throttle Body Hose by Mishimoto serves as a direct OEM replacement for the stock rubber hose.
The rubber throttle body hose, which connects the cold pipes from the turbo to the throttle body, can wear out due to oil, engine heat, and the design of the stock clamp.
These factors, combined with the constant movement of the cold pipes, place excessive stress on the rubber construction.
The deterioration of the rubber can result in a “boost leak,” allowing air to escape from the connector between the turbo and the engine, which robs the engine of horsepower and reduces overall performance.
Four hand-wrapped layers of silicone fortified with heat-resistant fibers are used by Mishimoto in the S4 Throttle Body Hose, ensuring a lifetime of durable performance.
