Any open cone filter will give you prolly 5-10 hp over the very restrictive,silenced stock air box...if you go to a full cold-air intake(cai) or fenderwall intake (fwi) you gain at least another 5-10 hp...the more fresh,cool air you can get is very much appreciated by your engine..specially if your supercharged.. even na (naturally aspirated) it helps a lot.. dont think of yourself as dumb not everyone knows all this stuff...Later
