BMC Performance Air Filter for Audi RS6 RS7 C7 (2013-2018) 4.0 TFSI

High-Flow Induction for the Audi C7 4.0 TFSI V8 Biturbo

Who It’s For: Engineered for Audi RS6 and RS7 owners running the high-output 4.0L Twin-Turbo V8 who want to maximize the efficiency of their forced induction system without compromising engine protection.

The Symptom: The Audi 4.0 TFSI powerplant (Engine Codes CRDB/CWUB) is a masterpiece of German engineering, but it is effectively breathing through a straw from the factory. The OEM paper filters are designed for extreme service intervals and quiet operation, which means they are dense and restrictive. This creates a significant pressure drop across the turbos, leading to slower spool times and a loss of potential power as the engine struggles to pull in the massive volume of oxygen required for peak combustion.

The Engineering Fix: This BMC Performance Air Filter replaces the restrictive paper element with a multi-layered cotton gauze media soaked in low-viscosity oil. This specific construction allows for a much higher air velocity while maintaining superior filtration. While the factory filter struggles with particles at 10 microns, the BMC system filters down to 7 microns. The "Full Moulding" design uses a single-piece rubber housing with no welded joints, ensuring a perfect seal inside your C7 airbox and preventing any unfiltered air from bypassing the media.

Why Mechanics Choose This Kit

• Enhanced Turbo Efficiency: By reducing intake resistance, the twin-turbochargers reach target boost levels faster, sharpening throttle response during mid-range pulls.
• Industrial-Grade Construction: Features an epoxy-coated alloy mesh that protects the cotton media from petrol fumes and oxidation, ensuring the filter holds its shape under heavy vacuum.
• Sustainable Performance: Unlike disposable OEM filters, this unit is fully washable and regenerable, designed to last the entire lifespan of your Audi with proper maintenance.
