Review on 🔌 Champion 7440 Spark Plug - Double Platinum Power (Pack of 6) by Doug Olson

Original Champion spark plugs on this Dodge have done 120,000 miles and the car still ran fine; why risk anything else as a substitute? I have always been a proponent of using original equipment wherever possible and that is what is required. I confess I would never put a European or Japanese engine in a Champ, but I won't put anything else on a Dodge. It's never been a bad choice and I've been doing it for a long time.
