jsut the filters alone are little to no help. they are capable of flowing more air, but the real restriction of stock TPI is the factory air boxes. it is a free mod to open them up and you can make little scoops for them out of about $2 of sheet metal, scrap aluminum flashing will do the trick actually.
those things all togehter would be plenty to take a race from side by side to you pulling a little.
