My N/a set-up which was really good on gas, and gave me a nice kick in power was as follows comptech ice box, comptech header, skunk2 intake, skunk2 stage 1 cams, hondata gasket, aem 5 bolt cam gears, apexi n1 exhuast, apexi VAFC 2( piggy back computer)and maybe be missing something, but the car was quick!, and best of all almost everything minus the cam gears and teh VAFC was street legal. ( I have the cams, the ice box{cold air intake}, and the header still.
