Performance Air Filter for Audi A6 / S6 C7 & A7 / S7 2.8 / 3.0 / 4.0 (2010-2018)

High-Flow Filtration for Audi C7 Platforms: Optimizing the 3.0 TFSI, 4.0 TFSI, and TDI Powerplants

Who It’s For: Engineered for Audi A6 and A7 owners running the C7 chassis (4G2/4GC/4GA) who are looking to eliminate the intake bottlenecks found in the 2.8 FSI, 3.0 TDI, 3.0 TFSI, and the heavy-hitting 4.0 TFSI S6/S7 engines.

The Symptom: The factory intake system on the Audi C7 platform is built for absolute cabin silence, which unfortunately comes at the cost of air velocity. The stock paper filter is dense and restrictive, creating a significant pressure drop as the engine climbs into the higher RPM range.

Whether you are waiting for the 3.0 TFSI supercharger to hit its stride or looking for that immediate low-end torque in the 3.0 TDI, the OEM element causes a "muted" throttle response and prevents the turbos from spooling at their most efficient rate.

The Engineering Fix: This BMC performance filter replaces the restrictive factory paper with a multi-layered cotton gauze soaked in low-viscosity oil, supported by an epoxy-coated alloy mesh. By reducing the filtration barrier from 10 microns down to 7 microns, we allow for a significantly higher CFM (Cubic Feet per Minute) while actually improving the capture of fine particulates.

The "Full Moulding" design ensures a single-piece construction without welded joints, meaning the filter won’t warp or leak under the high-vacuum pressures generated by the 4.0 TFSI twin-turbo V8.

Why Mechanics Choose This Kit

• Enhanced Induction Efficiency: Reduces the workload on the supercharger and turbochargers by lessening the vacuum restriction in the intake tract.
• Superior Filtration: Captures impurities as small as 7 microns, outperforming the standard 10-micron OEM paper filters used in the Audi A6/A7.
• Lifetime Durability: Unlike disposable filters, this unit is washable and regenerable, designed to last the life of the vehicle with proper maintenance.
