RacingLine Intake System / TRIFOAM FILTER / Audi S4/S5 B9 3.0T

Welcome to RacingLine's Audi B9 3.0 TFSI intake for Audi S4 and S5 B9. This stunning carbon fiber race-bred cold air Intake System has RacingLine's high-flowing, high performance Trifoam™ filter inside and is an essential upgrade to support your power increases. In testing, RacingLine's induction systems reliably give the highest airflow and greatest power gains of any intake on the market.

Developed and proven from RacingLine’s factory motorsport experience, this intake combines OEM-standards of design and quality with very significant power gains on uprated cars, all carefully hand-made in the UK. Airflow is no accident. Fully developed with F1-standard CFD programmes, it's no wonder so many high-powered cars choose RacingLine’s intake. The large airbox volume and maximized filter surface area are key to this, giving airflow capabilities to support increased power outputs without restriction. RacingLine’s unique High-Flow TriFoam™ triple-layer construction is widely regarded as the best filtration material on the market, and is the key to the power gains achieved. By enabling cold, dense air from outside the engine bay to reach the 3.0 V6's fuel metering unit more efficiently, the system delivers really impressive airflow gains - as much as 9% higher at peak power than that of the original intake system. By reducing turbo spool by up to 500rpm in some cases through the enhanced efficiency of the system, lightning fast turbo response is guaranteed. You'll hear the rich induction noise from this race-bred intake as soon as you accelerate hard. However, as a fully-enclosed intake, volume levels are well-contained. Please note that as a high performance intake, regular maintenance is essential to keep it at its very best.
