doing a top end rebuild today and upon pulling the plugs its looks as though mike had installed some champion copper plus plugs:shrug: i hate to waste them,they look brand new. but if they're going to do more harm than good i'll toss them.

I'd replace them on principle alone using Dodge plugs in a Ford. Seriously though I'd replace them with double platinums just so they dont need to be changed again any time soon.

#9 hated a few different plugs that were tried on it. The only plugs it seemed to like was the cheap-o Champion coppers. It ran much better and is still kickin with 150xxx :shrug:

They are fine, They just won't last as long though.

IMHO, don't worry about the plugs. Invest money else where
