High-Flow Panel Filter for BMW E36 & Z3 Platforms
The BMC Air Filter FB121/01 is a precision drop-in panel filter made for BMW E36 and Z3 models. With BMC’s Full-Moulding red rubber frame and multi-layer oiled cotton gauze backed by epoxy-coated alloy mesh, it enhances intake flow while filtering down to ~7 µm (versus ~10 µm for standard paper filters). It installs into the factory airbox—no trimming or tuning required.
Why Choose the BMC FB121/01 Air Filter?
- Improved Airflow & Filtration: Increased intake volume while capturing fine particulates (≥ 7 µm).
- Washable & Reusable: Serviceable with the BMC regeneration kit—no disposable replacements.
- Full-Moulded Frame: One-piece red rubber provides rigidity and lasting sealing.
- OEM Drop-In Fitment: Direct replacement into stock airbox—no mods needed.
