The BMC FB538/20 air filter is a free-flow filter for the Nissan GT-R, made with multilayer cotton gauze impregnated with low-viscosity oil. Its design minimizes the pressure loss of the air passing through the filter, while the Full Molding method forms the soft rubber into a single piece without bonded joints. The filter is washable and reusable.
