BMC Air Filter FB232/07 – Porsche 911 (1965-1973)  Performance Replacement Filter

High-performance BMC FB232/07 cylindrical air filter designed as a direct replacement for classic Porsche 911 and 914 airboxes. Washable, reusable and engineered to improve airflow while maintaining excellent filtration.

Product Description

The BMC FB232/07 Performance Air Filter is a premium replacement intake filter developed for classic Porsche flat-six engines. Designed to fit directly into the factory airbox, this cylindrical high-flow filter improves intake airflow while maintaining outstanding filtration efficiency.

Manufactured in Italy using BMC’s Full Moulding production process, the FB232/07 features multi-layer cotton gauze soaked in low-viscosity oil and protected by an epoxy-coated alloy mesh. This construction increases airflow while capturing particles as small as 7 microns, helping protect the engine while supporting improved throttle response and efficiency.

Unlike disposable paper filters, the BMC FB232/07 is washable and reusable, making it a long-term performance upgrade for classic Porsche models. Once cleaned and re-oiled using a BMC cleaning kit, the filter can be reused for the lifetime of the vehicle.

Perfect for restoration builds, period-correct upgrades, or drivers looking to improve airflow and reliability in their classic Porsche.
