Plastic Bosch = $32 after tax at Advanced Auto parts, just feed them the Bosch PN - or have them hunt for overpressure cycling valve or some such, it isn't categorized as BOV.

My take on them? They were good enough for turbo Porsches, they are good enough for you. I run one in the Saab elbow, which is about a 80 degree elbow, right before my TB. THere is no adjustment to speak of, but the spring tension varies around depending on which model they were designated for.

Hell, the Stoopra boys use them as an intermediate level upgrade.

It should work. I have a Volvo 780 bov. it bolts to the turbe but I'm going to put mine in the general location.

I now that the plastic ones suck or at least I wont use one of those couse the one on my Passat was stuck open a little bit and i was loosing boost.The guy at the dealer said it was common couse they have a plastic diaphram wich after a while they allways fail due to the heat.I paid extra and got one frome a TT.

Stock plastic BOVs on 2G DSMs can't hold over 16-18ish Psi without leaking, and anything over 18psi on the 3/S ( stealth ) plastic BOV is own to leak too..

1G DSM is prob. still the best "bang for buck". I paid $0.00 for my volvo BOV.
