anybody have a suggestion for the best spark for your buck on a v10?

 

Champion seems to run pretty well in the Dodges..

 

Champion truck plugs are decent. Most sparkplugs are essentially designed the same. You can try a cooler heat range plug if your interested in a bit more power or have a pinging problem.
Avoid Bosch platinum at all costs IMO nothing but problems

 

I'm on my 43 or 44th vehicle, and I've used bosch plats a lot and have never had a problem with them.

 

What about the new E3's? Do they really get the fuel mileage that they say?
