I'll have to check them out when I change out my plugs. All I know is im getting rid of the Autolite's.

Thread revival!
I got to thinking I need to change plugs again so I looked up what I replaced the OEM's with. Turns out I went with Champion single platinum 3318. I can't find how long these should last. I've put about 45,000 miles since then. I suppose I should pull one and see what they look like.
I need to do this over Xmas vacation too. What plugs ended up being best for the 4.7?Originally Posted by jcoulter

Roby wrote something about this on the other forum. The Champions are still
the best i believe.

Interesting this was brought up.....that and timely.
I have 12000 on these plugs now and removed one for inspection last month.
Looks like new.....no gap change....no discoloration.....nothing.
So....I guess I'll look again at 60k or 30k of service.
If what I see is any indication, these likely are 100k plugs as I anticipated.

That's a good idea I think I'll try to get around to pulling mine next week and see how they are doing. I can't remember what I put in
I went with the NGK V-Power plugs this time - changed 'em out about 3 weeks ago, & running great so far!
