Intake, B9 S4/S5 3.0T

This carbon fiber race-bred cold air Intake System features RacingLine's high-flowing, high-performance Trifoam™ filter. It's an essential upgrade for power increases, developed with F1-standard CFD programs. The large airbox volume and maximized filter surface area provide airflow capabilities to support increased power outputs without restriction. The unique High-Flow TriFoam™ triple-layer construction is designed for optimal filtration. This system delivers impressive airflow gains—up to 9% higher at peak power than the original intake system—and reduces turbo spool by up to 500rpm for lightning-fast turbo response. It also produces a rich induction noise during hard acceleration. The fully-enclosed design helps contain volume levels. Regular maintenance is essential.
