    Boomba bpv

    Quality product. Easy to install. Just have the right tool to get to the hose clamp at the bottom so you don't scratch the finish and your good. Boost level went up just a bit with no tuning.

    Looks good Works good

    Very nicely machined piece of aluminum that seems to be doing it's BPV job really well!! Machined groove with installed O-Ring on mating surface, so no gasket needed. If I had to do the install again I would protect the outer surfaces with painters tape to protect the anodize finish. Had some issues positioning the God forsaken spring clip and inadvertently scratched up some of the pretty black finish! Now in the process of an E-Tune and it seems to be holding higher than typical boost levels well!!
