Performance Air Filter for Audi A4 / S4 / RS4 B6 / B7, Seat Exeo (2000-2010)

High-Flow Induction Efficiency for the Audi B6/B7 A4, S4, and RS4 Family

Who It’s For: Designed specifically for Audi B6 and B7 chassis owners running the versatile EA113 Turbo and high-revving 4.2L V8 engine families.

The Problem: The factory paper air filter in the B6 and B7 airbox is designed for silence and long service intervals, not peak volumetric efficiency. This creates a significant bottleneck for the EA113 1.8T and 2.0 TFSI engines, which rely on rapid spooling, and the 4.2L V8, which requires massive air volume at high RPM. Stock filters typically only trap particles down to 10 microns, often sacrificing airflow for filtration density.

The Solution: This BMC performance filter replaces the restrictive stock element with a high-flow, multi-layered cotton gauze media. By utilizing a "Full Moulding" system, we provide a filter with no welded joints, eliminating the risk of breakage or air bypassing the media. This setup allows for filtration down to 7 microns while significantly increasing the CFM (Cubic Feet per Minute) capacity of the intake tract.

Why This is the Essential Induction Upgrade

• Advanced Filtration: Captures impurities as small as 7 microns, outperforming the standard 10-micron OEM paper filters while maintaining superior airflow.
• Full Moulding Construction: Engineered from a single mould with no welded joints, ensuring the red rubber housing fits perfectly within the factory airbox without air leaks.
• Washable and Reusable: Unlike disposable paper filters, this cotton gauze media can be regenerated using a standard cleaning kit, making it the last filter your Audi will ever need.
