Try them. What’s the worst thing that happens? You spent *** on them and don’t like them?
I run the champs myself. A bad air and fuel mixture is what will kill the plugs first, if it’s off. Which means it is more so important on the old rides. I just changed the Champs in my Dakota. 1 set in 6 years. However! That’s also a fuel injected engine with very good computer controls.
Plugs are cheap. Spend as you wish.
