Wondering what thoughts are on replacing my spark plugs at 58,000 miles? Just purchased my 2012 and don’t know much history.
Car does run very good but I’m just doing some preventative maintenance for optimum performance.
TIA

 

The stock plugs are usually NGK Iridiums and are scheduled to last 100,000 miles or 10 years whichever comes first.
The iridium central electrode is super tough and hardly wears down at all compared to conventional copper electrodes, that is why they last so long.
Also, assuming you have an AJ133 V8 in the car, the rear spark plugs can be a pig of a job to access and especially so on a supercharged version, and then there are the plastic/rubber valve cover covers which from all reports are extremely difficult to put back in place especially on the SC version.
So IMHO at 58k miles and running well I would not bother with a spark plug change.

 

Thank you, I believe that is sound advise at this time especially since its running smooth.
