Sale price$207.90

High-Flow Panel Filter Kit for BMW S55 & S63 Applications

The BMC Air Filter FB647/20 is a precision-engineered, drop-in twin panel filter kit for BMW M3/M4 (F80/F82/F83) and M2 Competition/CS (F87) models, with additional fitment for M5 (F10) and M6 (F06/F12/F13). Built with BMC’s one-piece Full-Moulding red rubber frame and multi-layer oiled cotton gauze reinforced by an epoxy-coated alloy mesh, it improves intake efficiency while filtering particles down to ~7 microns—tighter than typical OEM paper (~10 µm). Washable, reusable, and designed for a perfect OEM-style seal in the factory dual airboxes.

Why Choose the BMC FB647/20 Air Filter Kit?

  • Enhanced Airflow & Filtration: Higher intake volume with fine particulate capture (≥ 7 µm).
  • Washable & Reusable: Service with the BMC regeneration kit—ditch disposable paper filters.
  • Durable Full-Moulded Design: Seamless red rubber frame for rigidity and reliable sealing.
  • OEM-Style Fitment: Direct drop-in for dual factory airboxes; no tuning or modifications required.
