4.7 Spark Plugs

[Sal-XK]

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!
