The Twin Air 155701frx motorcycle air filter is pre-oiled with Twin Air BIO Foam Filter Oil. It features two layers of open-cell foam: the outer layer traps dust, dirt and sand, while the inner layer captures smaller particles and allows airflow. A third, flame-retardant foam layer is bonded to the filter.
The layers are bonded together to prevent particles from getting trapped between them. The flat, grease-free foam sealing surface fits against the airbox, while the special adhesive holds the filter’s seams together. The package includes a resealable bag.
