I have a volvo s60 2.5t 2007 auto. My car is stock and im planning on buying a bov for my car. I heard some people saying that bov can harm something that i didn't hear? I'm going to Sweden to buy exhaust system and computer chip from the company BSR jun 28, should i get the bov in Sweden or just get any Hks bov from my country? I was thinking of buying it here but Im unsure if im going for the bov at all. Any opinions with putting a BOV on the 2.5t?
