Greetings. First post here. Have a pristine 03 V-6, 4x4,TRD, manual trans extended cab. Would like to increase both power and economy without resorting to supercharger. Anyone have experience or recommendations re CAI, headers, exhausts from either TRD or others? My objective is to make it more efficient "and" powerful without increasing wear.

I know there's "no free lunch," but I am willing to spend money because I'm keeping this truck forever. [color:"black"] [/color]
