Spark plug recommendation….

[Highway]

almost time again to change spark plugs on my 2013 5.7. In the past i have just used the champion copper plugs, are the platinum any better for my engine? What plugs is recommended?

NKG 92145 Laser Iridium is well proven for 100k miles of service in the Hemi.

Don’t buy off of Amazon to avoid fakes.

I didn’t think the coils on the 2013 were compatible with Iridium plugs ?

I’ve seen people say that, but I’ve also seen people say they run NGK 92145 on a 2011 with no issue. One recommendation I read was to potentially replace a little sooner (80k instead of 100k) if you are on the older coil.

If you look up on NGK they say Mopar now recommends the Laser Iridium.

I put the iridium plugs in my 11 at 120k, but I changed to 15 coils. At 120k, I figured it was cheap insurance.

Your experience may vary

Copper plugs are still the most efficient plug,i'd stay with them,and change them at the reconmended intervals.
