Motocross Air Filter Sponge Reticulated Polyurethane 3Mm Polyurethane Air Filter Foam

The filters are constructed from two layers of high-flow, open-pore foam that are bonded together to provide maximum filtration and superior airflow. The coarse-foam outer shell with a fine-foam inner core, resulting in a one-piece design that permits continuous airflow.

Features:

• 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. Trapped particles can restrict airflow.
• They are constructed using a special adhesive that is unaffected by repeated cleaning, harsh solvents or gasoline.
