The BMC Super Quad - FM339/21 air filter is designed for demanding quads: it combines a multi-layer cotton media construction with a dedicated Superquader design. Intended to protect the intake and maintain engine breathing in dusty terrains, it must be installed with its specific pre-filter for optimal off-road efficiency.
Designed to limit the entry of dust, sand, and foreign bodies into the airbox, this filter offers a compromise between particle retention and airflow. Compatible with several Yamaha quad models (including YFM 350 Warrior and YFM 600 Grizzly depending on the year), it is aimed at riders looking for a robust replacement part that enhances engine protection during rides or sporting outings.
