TWIN AIR BACKFIRE / PF REPL FILTER PART# 150214FR

Description

Fused outer and inner elements prevent dirt and grime from being lodged between layers. Unlike twin air this can be a problem with two-piece designs. Trapped particles can restrict airflow and if dirt works its way into your engine a pinhead sized granule will gouge your cylinder piston and rings.
thick flat foam greaseless sealing ring ensures maximum contact with your airbox while acting as a breathable gasket for increased air passage
coarse open-pore foam catches airborn 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 withstands repeated cleaning. even with harsh solvents or gasoline
twin air filters are slightly smaller than stock filters to increase air space around the filter and improve circulation
