plugs and wires
e3sparkplugs dont get them gas milage = 0 HP increase = 0 money lost $40+ stick with stock plugs Sure there wll be dissenters, but that's been my experience.
i'd be careful of the E3's , i had em and loved em at first but after a couple of months one of them became fouled and left me stranded on the side of the road because the check engine light not only came on but started to blink, and the manual says to pull over and have it towed...i was waiting for my wife outside of wal-mart with the motor running and noticed it was idling weird then pulled away and noticed some engine fluttering then got on the highway and just felt like one of my cylinders wasnt working then the engine light came on.....i replaced it with another one and it ran fine but didnt want to take any chances so i swapped them out....
Are you kidding? I have had an engine light for almost a year....cannot find the problem...sometimes it blinks and dings and the Jeep runs really rough like its going to stall...and never for a moment did I consider calling a tow truck.... I don'r care what the manual says...LOL
