Performance Air Filter Cylindrical for 911 1965-1973

Superior Airflow for Porsche 911 Flat-Six and Mercedes-Benz Heritage Engines

Who It’s For: Designed specifically for the classic Porsche 911 and vintage Mercedes-Benz owners running the Porsche Flat-Six and Mercedes M110/M130 engine families. This is for the driver who values period-correct aesthetics but demands modern induction efficiency.

The Problem: Factory paper filters in these vintage airboxes are restrictive by design. The Porsche Flat-Six and the high-revving Mercedes Inline-6 engines rely on high-velocity air for optimal combustion. Stock paper elements are prone to clogging, degrade quickly with moisture, and typically only filter down to 10 microns, leaving your carburetors or mechanical fuel injection systems vulnerable to fine debris.

The Solution: We utilize BMC’s legendary cotton gauze technology to correct these legacy limitations. By using multi-layered cotton soaked in low-viscosity oil, this filter captures impurities as small as 7 microns while significantly increasing the volume of air reaching the intake. This results in sharper throttle response and a more pronounced induction note without sacrificing the protection of your vintage Flat-Six.

Why This is the Ultimate Upgrade

• Enhanced Induction Efficiency: Flows significantly more CFM than standard paper, allowing your engine to breathe better at the top of the RPM range where these classic engines make their power.
• Full Moulding Construction: Built using a proprietary "Full Moulding" system. Unlike cheap filters with glued or welded joints, this single-mould design prevents structural failure and air bypass.
• Lifetime Durability: The epoxy-coated alloy mesh protects against fuel fumes and oxidation. This is a "buy it once" part—simply wash and re-oil with a regeneration kit instead of throwing away paper filters.
