TWIN AIR AIR FILTER WITH CAGE HONDA CRF 300 L (2021-2022)

Twin Air Filter's design, high quality materials and superior construction deliver unbeatable performance and protection - and make Twin Air Filters the hands-down choice of more World & National Champions than all other filters combined. Coarse open-pore foam catches airborne dirt, grime and sand. Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage. Exclusively formulated adhesive ensures glue seams will not break down. Thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox, while acting as a breathable gasket for increased air passage. Fused outer and inner elements prevent dirt and grime from being lodged between layers, unlike Twin Air, this can be a problem with inferior two-piece designs. Trapped particles can restrict airflow. And if dirt works it's way into your engine, a pinhead-sized granule will gouge your cylinder, piston and rings like a bullet. Used Pre-Oiled Air Filter. The coarse outer Shell catches airborne dirt, grime and sand. The fine inner layer traps the little stuff. Twin Air filters are designed to increase airflow while ensuring the highest level of protection from dirt/dust. For Honda CRF 300 L (2021-2022).

Over 50 years ago, the sandy, gritty soil of The Netherlands – and the resulting engine failures – proved that single-foam and paper filters gave riders air flow, but failed at protection. Twin Air’s breakthrough, fused-dual-layer design (now widely copied) combined performance and protection. The fused layers of open-pore foam and fine inner foam trap even the smallest particles. The new, rounder design boosts airflow. So do the minimized seams made possible by a revolutionary micro-gluing process: Shorter seams = more foam = more flow.
