The Twin Air 150231FRX replacement fire-resistant pre-oiled air filter is designed for specified Honda CRF motocross and off-road motorcycle applications. It is pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco. The filter uses a coarse open-pore foam layer to catch airborne dirt, grime and sand before they reach the inner filtration layer.
A fine open-pore inner foam layer acts as a second filter to trap smaller particles while maintaining air passage. The adhesive is designed to withstand repeated cleaning, supporting ongoing filter maintenance. Its smaller-than-stock design increases air space and circulation around the filter. Manufacturer part number: 150231FRX. Vendor part number: 150231FRX.
