You don't think it's because Champion gives Dodge a sweet deal on plugs they buy in lots of 10,000,000?

 

I use the Autolite 3923's (copper) and have had no trouble with them so far. I re-gapped them after about 11K miles, and they had burned from .040 to .045 pretty consistently. The down side is that they probably need to be replaced about every 20-25K miles to stay good and fresh. The upside is that you'll spend about $12-$13 on all 8 of them at Wally World. I have heard nothing but good things about the Champion plugs, and they also make a "truck" plug with a thicker core. When I first came on this forum, the general consensus seemed to be, don't use anything except copper core on the Rams. But I say experiment...find what you like. I have tossed around the idea of using Accel race plugs next time...just need to figure out what heat range I would need. But for ease and peace of mind, I would go with the Autolite or Champion.

 

^^ I tried the Autolites and ended up with a Misfire #5 and my mileage dropped considerably. Platinum plugs are definitely out of the question.

 

I'm running the factory spec Champions with no problems. Next time I will try the indexing and see if that makes a difference.

 

I will have the very unique opportunity to index all of my plugs perfectly before the heads go on.

 

Ok, newbie question, What all is involved with indexing the plugs, and whats the benefits?

 

Well, I thought it was just making sure the gap pointed down by using magic marker on the insulator.

Thanks for the info. It was an interesting read.

 

i read an article before where someone dynoed b4 and after they indexed and there was no measurable gain
