The BMC Twin Air conical air filter is a universal intake element with a metal top, 70mm inner diameter and 140mm height. It’s intended as a replacement for intake setups requiring a 70mm inlet and a shorter profile. Confirm the 70mm ID and 140mm height with your intake plumbing; the metal top provides a firm mating surface for clamp connections on many universal intake tubes.
