Silicone Throttle Body Inlet Hose

The 034Motorsport Silicone Throttle Body Inlet Hose is engineered to enhance the performance of the B8 Audi S5 4.2L FSI V8 by replacing the restrictive factory corrugated plastic intake hose. Constructed from durable, multi-ply silicone with stainless steel wire reinforcement, this hose is built to prevent collapse under vacuum and maintain a smooth internal surface for optimal airflow. Its design eliminates the restrictive factory intake muffler, contributing to increased induction sound and noticeable top-end horsepower and torque gains. The hose also features a CNC-machined aluminum PCV connection nipple for seamless integration. Installation instructions are available via web or PDF. Early (2008) vehicles may require slight trimming of the engine cover for a perfect fit.
