Description
BMC High-Performance Replacement Air Filters (Set of 2) for Porsche 911 991 / 991.2
Enhance airflow, filtration efficiency, and long-term engine protection with this premium pair of BMC replacement air filters engineered specifically for the Porsche 911 991 and 991.2 platforms. Designed as direct replacements for the factory filters, these high-flow cotton gauze filters deliver superior performance while maintaining OEM fitment and reliability.
Two Filters Included and Required
This kit includes two high-flow BMC replacement filters, as required by the factory dual-intake airbox on the 991 series 911 models. Each filter installs directly into the OEM airbox with no modifications necessary.
High-Efficiency Filtration
These filters use advanced multi-layer cotton gauze soaked in low-viscosity oil to maximize airflow while capturing contaminants as small as 7 microns—an improvement over standard OEM paper filters that typically filter down to 10 microns. The result is:
-
Greater air volume reaching the engine
-
Improved combustion efficiency
-
Better long-term engine health
Advanced Construction & Materials
BMC filters are manufactured using a proprietary Full Moulding System, producing the iconic red filter housing from a single mould without welded joints. This eliminates structural weak points and ensures long-term durability, even under high-temperature conditions.
Additional design advantages include:
-
Epoxy-coated alloy mesh to prevent corrosion from fuel vapors and humidity
-
Long-life rubber seals with excellent adhesion to the OE airbox
-
Reinforced structure optimized for both street and track environments
Washable & Reusable
All BMC filters arrive pre-oiled and ready for installation. They can be washed, re-oiled, and reused using any BMC-approved regeneration kit, providing long-term value and reduced maintenance cost.
Airflow Performance
BMC filters are engineered for high permeability, increasing air volume through the OEM airbox without compromising filtration quality.
