Performance Panel Filter for Porsche 911 (K‑Jetronic)

The BMC Air Filter FB812/01 is designed specifically as a direct-fit replacement for Porsche 911 models equipped with the K‑Jetronic fuel system (1973–1983), including SC and Carrera variants (2.7 L & 3.0 L H‑6 engines). No modification needed—this high-flow filter installs directly into your factory airbox.

Manufactured in Italy using BMC’s full‑moulding process, this washable filter combines multi-layer cotton gauze pre-oiled media and epoxy-coated mesh to capture particles down to 7 microns—significantly finer than OEM paper filters (~10 μm). The result: improved throttle response, increased airflow, and prolonged engine life.

Why Choose the BMC FB812/01 Air Filter?

  • Optimized Filtration & Flow: High-performance cotton gauze with epoxy mesh filters more efficiently while allowing greater airflow.
  • Washable & Reusable: Simply clean and re-oil with a BMC regeneration kit—lifetime usability.
  • Molded Full-Frame Durability: One-piece rubber frame resists warping or failure in spirited driving conditions.
  • Easy OEM Fit: Installs precisely into factory airbox with no trimming or adapters.
  • Motorsport Proven: Built from the same Italian engineering used in Formula 1 and endurance racing.
