BMC air filters use a proprietary manufacturing process that molds the filter frame and sealing gasket in a single piece from soft rubber compound. This eliminates the weak points found in traditional welded or glued filter frames, ensuring a perfect seal and long service life. The oiled cotton gauze filter element flows more air than paper while still providing excellent filtration protection for your engine.
