Once the warranty runs out I will. Bought a k&n filter however Ford advised if I put it in then engine warranty would go bye bye as I'm not a mechanic. Furthermore, if it fouled the TPS then same deal, no warranty. I'm as scared of loosing warranty as the Mrs giving me hell, see I wasn't going to mod this one... hahahah Long term I'd like to upgrade intercooler piping, intake, hi flow cat and a tune.... oh and a better sound system, premium sound isn't worth its salt. Hopefully the end result would be a safe 300rwkw
