BMC High-Flow Panel Air Filter for BMW E81/E87 118d N47 Diesel, Part No. FA054/03

For E81 and E87 118d models with the N47 diesel engine (2004-2012) - not the N47D20A or later N47D20B variants - this BMC FA054/03 panel filter replaces the stock paper unit in the factory airbox.

• Direct-fit for N47-powered 118d only - verified fitment, no trimming or adaptation needed
• Washable cotton gauze media with low-viscosity oil: proven airflow gain over OEM paper on the N47’s restrictive intake path
• F1-derived rubber frame ensures full seal against the E87/E81 airbox lid - no bypass, no false air
• Epoxy-coated alloy mesh resists diesel particulates and under-bonnet corrosion better than generic filters
• Used by fast-road and track-day N47 owners chasing throttle response, not peak power - think stage 1 diesel, not decat or remap-dependent gains
