Hemi Spark Plugs
 

Hey guys, just getting ready to throw a set of plugs in the truck.

The NGK copper ones are 3.45 each and Denso platinum twin tips are 2.26 each.....

Denso FTW??? Who has swapped plugs and has a preference?

:fishing1:

Everything I've ever read says to use copper in the Hemi and nothing else. Not sure if that's the best answer but I've done 2 Hemi plug swaps and used oem NGK coppers both times. I'll also be doing the same when my truck is due for plugs in 8k miles.

I always use the copper NGKs. I know there were some misfire issues associated with the fancy platinum plugs in the past.

Got it!
