Spark plug recommendations

Stock engine. Just noticed my mpg's seem lower and doing a tuneup soon. Wondering if anyone has had better luck with a certain plug compared to others.

Ngk or champion low heat range plug is best for the hemi. Don't buy anything fancy.

Stick with OEM which is NGK or Champion, do not use antiseize on the threads of NGK.

Ok I was gonna ask how that platinum runs in trucks. I had a 2010 5.7l challenger that ran ****** with platinum so I only ran copper. Didn't know if the same was true with trucks

Need LOW HEAT range. So it's very important to stick to a cooper plug. Factory at that time was Champion.

As mentioned above - everything else will perform worse.

At least you're doing research instead of just throwing plugs in. I wish they didn't even sell other plugs for engine at the parts store. But then again, when you say you need 16, they ask, two cars??

This is my first dodge so I'll be honest, I was pretty confused myself. I'd never heard of 2 plugs per cylinder. I've always dealt with older chevy trucks with 1 plug per cylinder.
