AC Delco plugs in a ford?
Hello, I just picked up this 05 P71 and thought maybe I would go through it a little bit so I figured I would change the plugs first. My autoparts store never had autolite plugs just champion and ac delco for this particular car. So I picked up 8 of the delco platinum plugs. The car has 60,000 miles on it. I pulled out the first plug and it has motorcraft platinum`s right now and it actually looked to be in pretty good shape. I wonder if they are the original plugs, has anybody had a ford run good or bad with ac delco plugs. Maybe I should just leave them alone. Thanks for the suggestions.
