One common issue with the B5 S4 2.7T engine is that the stock throttle body hose wears out from oil contamination, heat and problems with the stock clamp design. Mishimoto's solution is available as a direct OEM replacement; the new silicone hose comes in black, blue or red and is guaranteed for life. To stop a boost leak near you, give Mishimoto a call.
