This Racingline intake is the highest-performing, race-bred cold-air induction system for the current B9 Audi RS4 / S4 & RS5 / S5
Simply the most sophisticated induction system for the current Audi S4/S5 & RS4/RS5 (B9) TFSI engines. Hand built in the UK to OEM standards of materials, workmanship and detailing with a stunning matte carbon construction. But more importantly, the giant Trifoam filter greatly increases the standard surface area to give massive airflow gains.
Racingline's latest Cold-Air Intake System kit for the current 'B9' Audi S4, RS4 and S5, RS5 enables cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for great power gains.
- Racingline's High-Flow TriFoam™ triple-layer construction is simply the best filtration material on the market, and is the key to the power gains achieved
- Each filter is handmade in the UK
- The intake uses a clever design which retains the original Audi lower box of the intake, adding in a replacement lid, TriFoam™ filter and front intake scoop
- By reducing turbo spool by up to 500rpm in some cases through the enhanced efficiency of the system, lightning fast turbo response is guaranteed. In Racingline's experience, no other intake kit gives higher gains
- It's not just about performance; the beautiful carbon weave of the intake will enhance your engine bay every time you lift the bonnet!
Giant Trifoam Filter
Racingline's unique Trifoam® filter construction is hand-made in the UK for the perfect filtration and minimum restriction.
Sound Quality
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.
Power Gains
Lots of cold, fresh air plus efficient filtration and huge filter surface area means power and torque gains support higher power remaps.
Precision Engineered for Perfect Performance
- A formed intake box specifically for the Audi B9 retains original lower box with carbon lid
