spark plug change at 60k nessary

13 model has 54000 ,was noticing that spark plug change is scheduled maintence at 60 k ,is it really nessary or just a dealer recommendation for them !!
I thought the days of changing plugs before 100 k was over
especially since the oem plugs are laser iridium

Looks like the interval is every 60K miles for the '13 with the laser iridium spark plugs. In the previous years, members say the spark plugs look pretty good when they're replaced, so you could extend the replacement interval a bit.

Might not want to extend too long.. gets harder to get them out of the head.

Of course if you are paying the dealer its their problem.

I'd probably change them I dont think 50000 or 60000 miles is a bad interval.. older ones I had to change every 25000 miles with copper plugs.

At least on the EJ motors, it's worth pulling the boots to check that the o-ring gaskets around the plug wells in the valve cover gaskets aren't leaking. Can't speak for the FB motors...

If the spark gap grows, ( and it does with miles) wont it get harder for the ign. system to fire?

Isn't that an unnecessary risk for ign. system longevity?
