Going down a degree recommended by you guys? Also switching back to copper instead of iridium?
I put in the Iridium plugs last time and really didn't notice any difference at all, and they were a bit more than all the others.
With my 5.0 i found that autolites were the best.
What do you guys use or believe are the best for the 4.6? NGK?
Really appreciate the advice.

Alexander
