Spark plugs

Will these be ok for the 5.7 Hemi. 2008.
Numbers don’t match in the manual but the shop guy says they’ll work
Also rock auto has these listed for the 2008 5.7

Champion RE14MCC4 plugs are the plugs that originally came with that year. Everything I've read on these forums points to anything but copper plugs making the 5.7L Hemi run poorly. So, those will work, I'm not sure how well.

Some people have had success running other plugs, but most have not; I'd stick with the OEM on a stock engine.

The NGK 5306 is a good spark plug for your hemi. I use them in my 2006. You should be quite satisfied with them.
