Air Intake Carbon Racing Filter Audi R8 4.2 V8 Quattro HP 420 (2006-2014)

Formula 1 Derived Induction for the Audi R8 4.2L FSI V8

Note: This is a custom, made-to-order performance component. Please allow a lead time of approximately 8 weeks for delivery. Once the order is placed, it cannot be cancelled.

Who It’s For: This system is engineered for the discerning Audi R8 owner utilizing the high-revving 4.2L FSI V8 engine. It is designed for those who demand track-ready thermal management and maximum volumetric efficiency from their induction system.

The Problem: While the factory intake is adequate for daily driving, the 4.2L FSI V8 generates significant engine bay heat that can lead to heat soak in standard plastic airboxes. Furthermore, traditional paper filters create a pressure drop at the high RPM levels where this engine makes its peak power, limiting the engine’s ability to breathe during spirited driving or track sessions.

The Solution: The BMC Carbon Racing Filter (CRF) replaces restrictive factory components with a 100% carbon fiber support structure. Unlike plastic, carbon fiber acts as a superior thermal barrier and allows for a thinner, more rigid internal geometry that optimizes flow dynamics. This keeps intake air cooler and maintains constant pressure within the air-box, ensuring the engine receives the densest oxygen charge possible.

Why This is the Ultimate Upgrade

• Optimized Flow Dynamics: Derived from BMC’s experience in F1 and MotoGP, the CRF design minimizes turbulence and maximizes air velocity into the plenum.
• Superior Thermal Resistance: The 100% carbon fiber construction withstands the extreme vibrations and high-temperature environments of the R8 mid-engine bay.
• Sustainable Performance: The multi-layer cotton filtration media is fully washable and reusable, outperforming OEM paper filters in both filtration surface area and longevity.

The Performance Promise

Professional Insight: Having worked on the Type 42 chassis for over a decade, I can tell you that induction is where the V8 truly wakes up. This BMC CRF kit isn’t just a filter; it’s a specialized tool for maintaining peak power when the engine bay starts to get hot. Note: Due to the increased airflow efficiency, ECU programming may be required to fully optimize the air-fuel mapping.
