Sorry, I just changed most (see new thread) of mine and I gotta agree with calling "BS" on changing them all in an hour. First time or not, it simply takes longer than that to get to everything, especially if you torque it all back up, use the plug goop and anti-sieze like you are supposed to.

To the OP: I just used the same exact plug make and model that came in the truck. And if you are going to do it yourself, expect it to take a while and be a major pain in the ***.
