Since we need 16 plugs on a Hemi engine which plug do you guys most use. OEM or better after market... I think my next service will be a expensive one...

Debating between putting after market quality plugs or the OEM.

Your taught are welcome

 

I can't remember where I read it but there was a thread either on this site or another where the general consensus was OEMs were the better choice. Several had mentioned some well known after market plugs didn't perform as well as the originals. OEMs work perfectly well I see no reason to change them.

 

if you search there are endless debates ...

 

Used the OEM plugs. I figured the truck ran fine for 30K. No need to experiment.
