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 used-pre-oiled-air-filter-smallcylinder, piston and rings like a bullet.
Adhesive withstands repeated cleaning
Smaller than stock to increase air space and circulation around filter
