For a 3.5L, I'd use NGK 7781 or Champion 3034 (I've used both in my 3.5L 300M)

If you have the 2.7L, then NGK 3381 or Champion 3232

The Champions are fine...in fact a lot of the 5.7's run bad without Champion plugs

I use the NGK copper plugs. Runs great, just don't buy into the expensive plug recommendations by the parts stores. Change every 30,000

Of course the V-6 is a whole different animal than the Hemi

The 2010 3.5L V6 requires platinum plugs.

Copper plugs are a bad idea and will cause issues if you use them.

It's weird how the V-8 likes copper plugs and the V6 doesn't...are the ignition systems that different ?
