I've had good luck with Champion Truck Plugs and NGK V power plugs. The Autolite 3923 never ran right in my engine after about 500 miles.
The Projector tip on the stock champion plugs is longer on the newer second gens that the older ones (99 was the change I believe???). I think that might be the reason the autolites didn't work as well. They have a shorter snub nose and the newer engines might "prefer" the longer tip.
This is just my personal experience. Your experience may vary.

I had a experience like above. They just never seem to run right after a month or so. Not sure how many miles I drove in that month.
I've never tried NGK plugs in the Dodge but I like them for the Honda's which they are OEM and the bikes.

The Autolites ran like shiat in my engine. Mileage went down and I was getting a misfire on #5. I switched back to the stock Champion plug and everything smoothed out.

The NGK V-Power ZFR5F11
(stock number 2262, resistor inside 4,000 ohms)
are very good plugs, except for a cylinder that is pinging
The short nose design Autolites 3923's are best used in the cylinder that is pinging.
