Performance Panel Filter for BMW 1, 3 & X1 Models

The BMC Air Filter FB518/08 is a precision drop-in panel filter compatible with a range of BMW 1 Series, 3 Series, and X1 models. Engineered with BMC’s Full-Moulding red rubber frame and layered cotton gauze media backed by epoxy-coated mesh, it improves intake flow while filtering fine particles (~7 µm). It installs directly into the factory airbox — no cuts, no mods.

Why Choose the BMC FB518/08 Air Filter?

  • Improved Airflow & Filtration: Higher volume intake while capturing fine particulates (≈7 µm) vs standard paper filters.
  • Washable & Reusable: Serviceable with BMC’s regeneration kit — no disposable replacement needed.
  • Full-Moulded Frame: Single-piece red rubber frame ensures rigidity and long-lasting sealing.
  • OEM Drop-in Fitment: Direct replacement in factory airbox — no trimming or tuning required.
  • Engineered Durability: Epoxy-coated mesh protects media from fuel vapors and oxidation.
