diverter valve

  1. MKIV GTI

  3. MKIV GTI
    I've been hearing that a blow off valve for the 1.8's will ruin the turbo life but I'm not sure. Ive heard a ton about the R1 Apr diverter valve and am wondering if that would be the better route rather than a blow off valve. Thanks [hail vw]

  7. MKV GTI
    As some of you may know already, I'm working on my K04 build. Although not necessary, I decided to do a little custom work and fabricated my own (what I'm calling) DV "cap". The K04 does not have a port for a DV and to keep the ECU happy, the stock DV should remain plugged in so there is no...
