High-Flow Panel Filter for BMW N54 Twin-Turbo Models

The BMC Air Filter FB494/20 is a precision drop-in single panel filter for BMW N54-powered cars. Built with BMC’s 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 airbox.

Why Choose the BMC FB494/20 Air Filter?

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