Great product that has only one flaw IMO, the gasket from the flange to the TMIC is crap. If you have to remove your intercooler for maintanence or turning a wrench I notice more wear every time as it is a I believe a cloth type gasket, not impressed. But the actual BOV is awesome does a great job. When installing leave out the adjustment washers, with one I was getting flutter, works fine with none. For anyone that wants a BOV that is loud this is NOT the BOV you want, yes it does make the typical BOV sound but not loud at all so this perfect for people who dont want to draw attention.:tard:
