BMC FB01029 Replacement Air Filter for AUDI S6 (C8) / S7 (4K)

Replacement Cylindrical Air Filter

The cylindrical air filter—often called a “replacement air filter”—is designed to drop into your vehicle’s original airbox in place of the OEM element. Constructed from high-performance materials, it delivers increased airflow while providing superior filtration down to 7 microns (compared to the OEM’s 10 microns), ensuring that even the finest impurities are captured.

Key Features:

• Full Moulding construction: produced in one piece with no welded joints, preventing weak points and breakage
• Durable, long-life rubber flange that bonds securely to any airbox shape
• Multi-layer cotton gauze media, oiled with low-viscosity filter oil
• Epoxy-coated alloy mesh for protection against fuel vapors and moisture oxidation
• Pre-oiled and serviceable—wash and regenerate with the BMC regeneration kit

Technical Specifications:

• Shape: Cylindrical
• Base inner diameter (outside width): 91 mm
• Base outside diameter (outside length): 143 mm
