I just bought some Autolite 3923's and some 8mm Summitt Wires.. I've heard alot about both the 3923's and the 3924's but I decided to give the 23's a try!! I'm hope they perform as well for me as the rest..If not I will still have the Platinum+4's to put back in...I defenitley upgraded my wires, I have 7mm wires on there now.. .40 is the gap for the 3.9 correct?

 

On a stock ignition, .40 should be fine but check the emissions sticker on the bottom side of the hood to be sure. You should get a nice smooth idle and good power and acceleration out if the 3923's. I think they do a little better on MPG too.

I have never tried autolite I have always used Bosch, I use bosch In my trucks and atvs they work great for me. It all depends on a persons perspective.

 

Thanks for the info now I'm ready to see how they work for me..

 

I have had my fair share of mopar and they will keep going like the energizer bunny and treat them like a fine woman I had a dodge ram van with slant 6 lasted almost 450,000 miles and strong until my wife hydroplaned into a tree.
I now have a 95 dakota with 135,000 miles and champion spark plugs are factory and the best. YEARS TESTED

 

Dodge will give you what you want as long as you treat her like a fine woman. Champions are factory and the best. YEARS OF MOPAR XPERIENCE!!!

 

i got platnum +4's in my 2000 dak 3.9L, and the truck absolutely loved them.. i love them too, no gapping. i am rebuilding the truck now, and i am starting to focus on the motor, i will pull them out, inspect and post a pic of em. after 8k miles on them.. they should still look pristine.. haha.. then again, if not, gives me reason to tear down the motor
