SLE Intake System – 2.0T B9 Audi A4 / A5 with Silicone Turbo Inlet and Aluminum Heat Shield

SLE Intake System – B9 Audi A4 / A5 (2.0T) with Silicone Turbo Inlet and Aluminum Heat Shield

The SLE Intake System for the B9 Audi A4 and A5 2.0T is designed to improve airflow, reduce restriction, and bring a more aggressive sound to your daily drive. Featuring a large velocity stack air filter, high-flow silicone turbo inlet hose, and aluminum heat shield, this intake system increases power, sharpens throttle response, and adds a sportier engine tone.

The 3.5” multi-ply silicone inlet hose eliminates factory bottlenecks while the heat shield blocks engine bay heat for cooler, denser intake air. Combined, they improve performance and create a louder turbo spool and diverter valve sound that enhances driving excitement.
