Racingline Carbon Fibre Air Intake System RS4/RS5 (B9) 2.9 V6 TFSI

Racingline Carbon Fibre Air Intake System – Audi RS4/RS5 (B9) 2.9 V6 TFSI

Unlock more power, sharper throttle response and a striking under-bonnet upgrade with the Racingline Carbon Fibre Air Intake System, designed specifically for the Audi RS4 and RS5 (B9) fitted with the 2.9 V6 TFSI twin-turbo engine. As an authorised UK Racingline dealer, we supply this intake as one of the most effective and well-engineered bolt-on upgrades available for these cars.

This kit replaces the restrictive factory airbox lid, filter and air scoop with high-flow carbon fibre components, allowing your engine to draw in a greater volume of cool, dense air from outside the engine bay. The result is genuine power gains, faster turbo response and a noticeably more eager feel when you push on.

TriFoam™ Filtration: The Heart of the System

At the centre of the kit is Racingline’s TriFoam™ filter, a triple-layer laminate of open-cell polyurethane foam, hand-made in the UK. It strikes an excellent balance between high airflow and effective filtration, protecting your engine while letting it breathe far more freely than the standard paper element.

Why It Makes a Difference

The standard Audi airbox is designed with noise reduction and mass-production in mind, not maximum performance. By keeping the original lower airbox (which sits in a well-positioned cool air feed) and upgrading everything above it, Racingline have created a system that is both effective and straightforward to fit.

• Significant power and torque gains across the rev range
• Reduced turbo spool time, in some cases by up to 500rpm, for sharper throttle response
• Genuine carbon fibre lid and air scoop for a premium under-bonnet finish
• Reusable, washable TriFoam™ filter for long-term value
• Retains the factory lower airbox for a clean, non-intrusive installation

Sound and Driving Feel

Because the intake is fully enclosed, you get a richer, more purposeful induction note under hard acceleration without the system becoming intrusive at cruise. It is a noticeable improvement over the muted factory sound, but remains refined enough for daily driving.

Build Quality and Finish

The intake lid and air scoop are made from real woven carbon fibre with a deep, lacquered finish. It looks every bit the part of a serious performance upgrade and complements the styling of the RS4 and RS5 engine bay beautifully.
