Is anyone here running this ebay BOV? Looks a little nicer than the Bosch and it comes with different springs
Black Aluminum Bypass Valve for Turbo Saab Audi Porsche VW Diverter Valve | eBay

I am looking at boosting my car no more than 12psi, any suggestions? I read the Bosch ones leak over time and the diaphragm cracks

 

I've got one of this on my previous setup
very loud, but it has an o-ring that sometimes get straight to compressor inlet, and without it ==> bov leak when in boost

if you don't care about this "little" problem, you can get the most inexphensive ebay bov
in the world

 

Well, I ended up buying the mitsubishi bypass valve part number MD162219 that Begi sells. It was $54 plus shipping at the Mitsubishi dealer.
