Nothing is better than good ol OEM (i.e. Motorcraft). Don't let anyone tell you otherwise.
Thanks for the reply celly. I'm just tryin to figure out what all the recommended brands and parts are for the Explorer as I just bought it and have previously been into Japanese cars, so its a pretty different ball game.
I used to change my plugs twice a year in my cars but after seeing how hard it was to do the plugs on the X last night i'm not sure if I want to do it that often haha. That back plug passenger side was pretty gnarly to get at. Even with taking the wheel well splash shield off.
