BMC High-Performance Replacement Air Filter Set for Porsche 911 991/991.2

Unlock the full potential of your Porsche 911's naturally aspirated flat-six with this premium BMC dual air filter kit. Engineered for the 991 and 991.2 chassis—the generation that perfected everyday supercar performance—these washable cotton gauze filters deliver the unrestricted breathing your precision-engineered engine demands.

Why Your 991 Deserves BMC

The 991-generation 911 represents Porsche's most refined balance of track capability and daily usability. Whether you're carving canyon roads in your Carrera S or pushing lap times in a GT3 RS, your engine's performance begins with clean, abundant airflow. This complete two-filter set replaces both factory units in your OEM airbox, transforming intake efficiency without compromising the engineering integrity Porsche built in.

Dual High-Flow Filtration

This kit includes both filters required for your 991's dual-intake system. Each BMC filter captures particles down to 7 microns—30% finer than standard paper filters—while dramatically increasing air volume. The result? Sharper throttle response, improved combustion efficiency, and enhanced engine protection that keeps your flat-six running strong for years to come.

Race-Proven Construction

BMC's exclusive Full Moulding System creates each iconic red filter from a single piece with zero welded joints, eliminating weak points that plague inferior designs. Multi-layered cotton gauze soaked in precision-formulated low-viscosity oil maximizes flow while maintaining filtration superiority. An epoxy-coated alloy mesh shields against fuel vapors and humidity, ensuring consistent performance in any condition.
