ok Im lost I thought if you let hot air into you intake you will lose power I thought it was the cooler the air the better under my hood gets HOT and the setup for this hiflow intake allows hot air from the engine to enter the intake how would you get a 8%-10% gain by letting more hot air into the intake and for $99 I DONT THINK SO I think Ill go to Autozone buy the cheapest cone "hi flow" filter and a couple peices of sheet metal and some pop rivets and maybe a can of spray paint and maybe if Im bored some termal wrap for less then $50 and make a box to put the filter in with a sheet metal duct to let MOSTLY cool air in and cross my fingers for a 5% gain then later on and some mandrel bent pipes for smoother air flow would anybody here be willing to buy it for $75 plus shipping? minus the piping because I could make them easy after I make the first one and paint it just about any color
