Product Description

The BMC FM788/04 Performance Air Filter is engineered to replace the restrictive stock paper element on Honda Grom 125 and MSX125 motorcycles from 2013 through 2020. This high-flow panel filter uses premium multi-layer oiled cotton gauze media to allow increased airflow into the engine while still maintaining effective filtration, helping improve throttle response and overall engine breathing during daily commuting or spirited riding.

Built using BMC's full-molding process, the FM788/04 features a durable one-piece design without welded seams for enhanced strength and reliability. The epoxy-coated alloy mesh protects the filtration media from fuel vapors and moisture, and the washable, reusable filter element offers long service life and reduces maintenance costs compared with disposable OEM filters. It installs directly into the factory airbox with no modifications required. Coverage is confirmed through the listed years; fitment for later model years, including 2025, is unconfirmed at the time of listing.
