SLE Intake System – B9 / B9.5 Audi S4 / S5 (3.0T) with Silicone Turbo Inlet and Aluminum Heat Shield

The SLE Intake System for the B9/B9.5 Audi S4 and S5 3.0T is engineered to improve airflow, reduce turbo lag, and dramatically enhance induction sound. Featuring a large velocity stack air filter, high-flow silicone turbo inlet hose, and an aluminum heat shield, this intake kit delivers noticeable gains in horsepower and torque while sharpening throttle response.

The multi-ply silicone inlet hose eliminates the airflow restrictions and collapse issues found in factory piping, while the heat shield keeps intake air temperatures down for consistent power. On top of the performance gains, expect aggressive turbo spool and diverter valve release sounds that completely transform the driving experience.
