BMC FBPF55-120L Universal Conical Performance Air Filter 55mm Left Offset

The BMC FBPF55-120L is a universal conical performance air filter designed as a direct replacement for the OEM airbox on motorcycles, scooters, and powersports applications. Featuring a 55mm inlet diameter, 120mm filter length, and a left-offset (angled left) inlet neck, this filter is engineered to bolt directly onto carburetors or intake stacks where a left-exit orientation is required. A chrome metal top cap gives the filter a clean, finished appearance under the hood or on an open-air intake build.

Key Features:

• 55mm inlet diameter with left-offset neck for specific carb/intake fitment
• 120mm overall filter length for increased filter media surface area
• Multi-layer oiled cotton gauze filtration media captures particles as small as 7 microns
• Chrome metal top cap for a premium, finished appearance
• Inlet neck material is highly resistant to mechanical and thermal stress — no heat deformation or cracking
• Factory pre-oiled and ready to install straight out of the box
• Washable and reusable — clean and re-oil with a BMC regeneration kit to restore like-new performance
• Replaces the restrictive OEM airbox for improved airflow and throttle response
