In my experience with Chrysler vehicles, stick with what came with it. That means Champions. Best runners.
If its an 02-04, and has NGK's, put them back in it. Thats what it was designed for.
Dont believe the hype on the bullshit spark plug ads. I cant tell you how many times I have put other brand plugs, such as +2's, +4's, etc etc into various vehicles and have had an issue with them. Throw what it calls for back in, guess what, runs like a champ. Its an LH car, not a racecar, stick with what it needs.
