how does blitz BOV sound? is it recommended for cars?
Look on youtube for video clips. You don't need one if you don't have a turbo if that is what you mean by "normal" sedans.
You cant even install it on a non-turbo. It wouldnt do anything even if you managed to weld it in place. As for how it sounds, it depends on which one you get. They can be engineered for extra louder sounds. But generally Blitz ones sound good.
