Doing an almost 100k mile tune up on our 2010 Grand Caravan, and not sure what spark plugs to go with. I've always had GM's and always just gone with AC Delco's. Would really just like to stick with an OE type replacement, Bosch, NGK?
i believe Champion plugs were used at the factory by Dodge.
Fords were Autolites.
GM uses AC Delco plugs, which are made by whoever is cheapest on a given day.
