I did the same thing yesterday, but my Dart just turned 46k miles.

Yours look similar to mine with quite a bit less miles.

Yeah, I agree. They looked a little worse than I expected. I checked the gaps of the plugs I pulled, they varied from .038 to .046.

 

[jshillin]

Wow. That's wild they were gapped different like that. Have mine at .45. How is it running now, smoother?

I've only driven about 5 miles since I did it, so I can't really say for sure.

I read that yours smoothed out the idle and I'm not sure I'll be able to tell much of a difference since I'm running Deyeme Racing Mounts.

What's the difference with the mounts?

They are filled with a flexible urethane so they don't wear out fast like the others and doesn't allow the engine to move so much. That means it puts more vibration into the car.

 

[jshillin]

Good to know. Do you feel more vibration?

Yeah, at idle you get some vibration. The stock mounts were junk when I bought the car with 40k miles, I was getting a clunk when accelerating hard at any speed and vibrations at different speeds as well as idle. I can live with some vibrations at idle to fix the end moving so much and clunking.

So far I've had no issues but I will keep this in mind. Did you replace them all?

Yeah, I replaced them all. The bottom mount wears out and then the sides mounts flex a bunch of it wears them out next. If I had to do it again, I'd get the Deyeme Lower Flex mount and OEM for both side mounts.
