I used the Champion Truck Plugs for years ... never had an issue with them. This 'go-round' I am going to try some NGK plugs. I was looking at the Autolite Iridiums, but at 5.99 a pop ... I handed them back to the counter person. 
For wires ... my nod goes to Magnecor. Excellent product !

The E3's don't block the kernel as most standard electrode plugs do. They allow the fire from the plug to shoot directly into the combustion chamber without the electrode blocking the way.

I have been wanting to put these into my Trans Am, but the engine compartment was tight stock, and now with the long tubes, its a little more tricky overall

I have the Accel Kit with an accel coil. Been running them for almost two years with no problems. I have been thinking of switching the plugs to the E3's as I have herd very good thing about them.

NASA quadruple Platinum +6 split V Ultra Arc super magnums with flux capcitor. Better MPG's , throttle response, a few more horse and the best part is that my tires are a little more balanced.
