A friend of mine has a mad ass integra but it is NOT turbo and still makes the WOOSHHHHHHHHHH noise as though he has a blow valve. He told me that he bought a throttle body spacer from ebay for $30 and that is what is making that noise.
Does anyone know what that throttle body spacer is?
My car is a twin turbo and has a blow valve with another little valve thing attached which silences that WOOSH (which I HATE) but it makes more of a strange sucking noise which can be heard quite loudly from my vents on the bonnet. It's quite odd...
