What plugs for 5.4L????
I have a 2003 F150 Supercrew FX4 5.4L. It has 136,500 miles on it. I just purchased the truck and was gonna do a tune up. What plugs should I use? I'm gonna stay with Motorcraft but the guy at AAP advised that the truck CAME with Single Platinums; but they also had Double Platinums and Platinum Iridiums. Would either the double platinum or platinum iridiums provide any better MPGs, performance etc?? Or do i need to stay with the single platinums??----DirtySCREW
