High-Flow, OEM-Fit Panel Filter for BMW Diesel Platforms
The BMC Air Filter FB479/20 is a precision drop-in panel filter for popular BMW diesel applications across the E8x 1 Series, E9x 3 Series, and E84 X1. Using BMC’s Full-Moulding red rubber frame and multi-layer oiled cotton gauze backed by epoxy-coated mesh, it increases intake efficiency while filtering down to ~7 µm (tighter than typical OEM paper ~10 µm). Installs directly in the factory airbox—no cutting or tuning required.
Why Choose the BMC FB479/20 Air Filter?
Airflow + Filtration: Higher intake volume while capturing fine particulates (≈7 µm).
Washable & Reusable: Service with the BMC regeneration kit—ditch disposable paper filters.
Full-Moulded Seal: One-piece red rubber frame for rigidity and long-term sealing.
OEM Drop-In Fitment: Direct replacement—no modifications needed.
Durable Construction: Epoxy-coated mesh resists fuel vapors and oxidation.
