Would these work any better than the ones reccommended my Edelbrock(Champion RC-12YC)? I am currently using the Champions and wonder if they are a good choice or not.

Zach,

I've found the NGK plugs to work well in Chrysler engines. Everyone has their own preference but if you're unhappy with the champions then you can allways switch. INMO, the ngk is a superior plug.

Seems like the spark box is the #1 thing-the spark plug fires as good as the power going in it-I like MSD 7 units - not cheap but puts out a good strong spark. With that box any brand plug will work good.

I have had rpoblems with NGK , they are very sensitve to fouling & will not clean up but if the car is correctly tuned this should not be an issue
