The dreaded spark plug question
Hello everyone,
Yep, I am bringing up " The dreaded spark plug question"
I have a 2001 Durango SLT+ with the 4.7L engine. I have been digging through older posts and (haven't seen alot of them dedicated to the 4.7L but) from what I am seeing is that the preferred replacement is the Champion Copper plugs (439) gaped to .40. Is this still true today? I also have seen that platinum plugs should be avoided like the plague, are the Iridium Champions also taboo??? I know plug technology has changed over the years and I want to do right by my Durango.
Thanks
Steve
