The Detroit Tuned Bypass Valve is a re-worked brand new OEM 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. Perfect for the aggressive driver or racer. Expect a very minor loss in fuel economy, and a great improvement in throttle resolution and smoothness. Every valve comes with full how-to instructions with great photos. Easy to install in about an hour.

    hello arron love doing business with your company but I didn,t recieve instruction with this product. Thanks Charles.
  • Author: Thom D.
    Ordered this to replace my OEM bypass valve and glad I did. Original one was just caked with black grease/soot/carbon/ was just bad.

    After installing the new BPV from Detroit Tuned, I notice a slightly quicker throttle response and a significant reduction in the "YOYO effect" (slowing down, foot off throttle, feels like it speeds up for a second).

    I highly recommend this modification as it's (relatively) inexpensive and only takes about three or four hours for someone of low experience to install.
