BMC Air Filters for Mercedes A-Class, CLA, GLA & GLB

Shop genuine BMC washable air filters for Mercedes-Benz A-Class, B-Class, CLA, GLA, and GLB applications, including standard turbocharged models and AMG 35/45 variants across multiple generations.

Factory-Airbox Fitment

BMC replacement filters install inside compatible original Mercedes-Benz airboxes without requiring a complete aftermarket intake system.

Washable & Reusable

BMC’s oiled cotton-gauze filter media can be cleaned, dried, re-oiled, and reused with the proper BMC maintenance products.

Chassis & Engine Selection

Mercedes fitment can change by chassis, engine, model year, AMG trim, hybrid status, and original airbox. Confirm the complete application before ordering.

Compact Mercedes platforms use different filters by generation and engine. AMG 45 applications are especially important to match by chassis and BMC part number rather than model name alone.
