4.7 V8 spark plug recommendation

808ram1500 · Jul 4, 2017

What type of spark plugs are recommended for a 4.7 V8. Is there anything better than the stock plug or just go with stock plugs?

I went with the Copper Champion original plugs when I had my '05. In fact I changed them just months before trading it for the '16.

The gap was about 1/4" and since I owned the truck since 75,000, I believe they were the original plugs, and it was at 120,000 when I changed them.

Maybe not.

I did Mopar plugs at 60k. The original plugs were fine when I pulled them out.
The Mopar plugs are ngk I think

You did all 16 plugs or just the top ones?

I did just top set, I'll do all 16 at 110-120k, supposed to do them at 90-100k but going to do them all at once. The bottoms are iridium if I'm no mistaken

My '05 only had 8.

That was enough......

My truck has 80k on it now. I bought it at 67k. I don't think precious owner did any plugs so I will be doing them soon. Hopefully don't run into problems.

You shouldn't... Might be a little early but might as well do all 16
