The ones you pull out of your heads (stock).

Please go over the FAQs at the top of this section as it will cover all of those Qs you have.

 

ngk v-power....which would be one choice i believe in the faq section

 

just put in Denso Iridium Powers in mine....seems to be running nicely

 

Pulstar...the hemi loves it

 

Basic coppers are gonna be your safest and most reliable plug. Going to a fancier plug won't gain any HP and may or may not give you driveability issue's. Some experience trouble and others don't but the Hemi was designed for basic coppers. Fancy plugs just allow you to drive further. That's it.

 

I put OEM replacements in mine and it runs great. Even though some others use high-end plugs and seem to be okay with it, the overwhelming majority opinion on this site seems to be that the hemi likes the old copper core standard plugs better than anything else. And, with 16 plugs to buy every 30,000 miles, why spend the extra money? I could see if it there was a recognizable mpg and/or performance gain or more longevity between plug changes, but there doesn't seem to be any evidence of any of those.

 

Champion is best...says so right in the name.
