I've got about 38,000 miles on my jeep. I'm sure the plugs are original, do you guys think it would be worth my while to change them? I just watched the video of that weird guy on youtube change his plugs on his 4.7 wk, they looked really bad and gapped themselves to double the stock specs. That's the reason why i ask.
haha, thanks Scott, i was reading that thread, while you posted this reply. I'm really just trying to decide if it's worth my time. I'll probably do it this weekend. About an hour or so?
