BMC Air Filter FB812/01 – High Performance Panel Filter – Porsche 911 2.7L & 911 3.0L SC
High-performance BMC FB812/01 replacement air filter designed for Porsche 911 models with K-Jetronic fuel injection (1974–1983). Washable, reusable cotton gauze filter offering improved airflow and engine protection.
Product Description
The BMC FB812/01 Performance Air Filter is a direct-fit upgrade designed for classic Porsche 911 models equipped with the K-Jetronic fuel injection system. Replacing the restrictive factory paper filter with BMC’s high-flow cotton gauze design improves airflow to the engine while maintaining superior filtration efficiency.
Manufactured in Italy using BMC’s proprietary Full Moulding process, the FB812/01 features a seamless rubber frame for increased durability and perfect sealing within the factory airbox. The multi-layer cotton gauze filter media is pre-oiled and supported by an epoxy-coated alloy mesh, allowing improved airflow while capturing particles as small as 7 microns, finer than typical OEM paper filters.
Unlike disposable paper filters, the BMC filter is fully washable and reusable, making it a long-term performance upgrade that reduces maintenance costs while maintaining optimal engine breathing.
Ideal for enthusiasts restoring or upgrading classic air-cooled Porsche models, the FB812/01 provides improved throttle response and enhanced intake airflow without any modifications to the factory airbox.
