when i saw the picture this intake i was just like :lol: and flipped through it. lol man was i dumb. when i read about it a little later it claimed about 9rwhp gain and 9lbtorque or something around there. i was just wondering if this intake even comes with a filter. i know it works with the OEM filter box but how the hell does that tube give 9hp/lb? does it come wit a piggyback ecu maybe? or a another air filter? i also heard the TRD or BLITZ / toms or watever drop in filter claimed around 8hp gain. dunno if its rwhp. any of you have the Pro Lex Silent Flow Intake?
