The DT Bypass Valve is a re-worked brand new OEM MINI bypass valve that is modified to eliminate the "Yo-Yo" in early year ('02-'04) Cooper S's, but is available for all year Cooper S's. This BPV uses a stiffer return spring, resulting in quicker boost generation, and thus quicker throttle response and transitions. The butterfly assembly is also adjusted to close fully, allowing for maximum boost. Expect a loss in fuel economy, and an improvement in throttle response.
