Got a friend (he's from Liberia, and not really up on Jeeps!!!) with an '06 5.7 WK that needs plugs. I'm gonna help him, so any recommendations is welcome!

BUMP, are you guys changing your plugs at 30k?
just changed mine at 90k, just rolled 120k

I changed mine at around 90k, and dang were they shot, hahaI have no idea is any of the previous owners had ever changed the plugs. 30k seems reasonable to me. Heck why not? <$20 for Champion stock replacements.

Changed mine @ 60k, because that's when I bought it. ALMOST to 80k now - got a while 'til the next batch.Originally Posted by paroxysym

If you are running OEM copper plugs, change every 30k miles. If you run iridiums, you can change every 100k miles!

Well that's what I THOUGHT, but I wasn't sure. I switched to NGK iridiums when I changed mine at 60k.

I have the 4.7 with the copper plugs. can somebody help me verify what the gap should be? I am double checking. thanks
Easiest way to double check is look at the placard on the underside of the hood. It'll list the gap and spark plug part number under the engine specs.
