design but that doesn't mean that your wrong either. I do see your point like I said earlier but if you could split one down the middle *I think* you would understand what I was trying to say but then maybe not? Unlike most BOV designs the Apexi BOV has 4 holes to let out air into the atmosphere and not one outlet. The Apexi BOV is also designed to let out as much air with the adjusting screw down as well as up. If you ever get your hands on one open it up and I think you'll see what I mean. I wish, I was more articulate.
