Autolite XP Iridium spark plugs?
Dealership didn't have the plugs in stock so I went to advance and the Autolites are what they had. Any problems running these iridium plugs? I'm going to pull my plugs this weekend to check, but I'm thinking they are fouled because the car started cutting out at high rpm a few times over the past week or so and I would like a replacement set.

Don't.

If the car is not tuned, the misfire is normal.

Go to dealer, get second reflash. It might help. I also had to add a drop-in filter in order to get rid of the hesitation.

I got the reflash about a week or two ago. After the reflash is actually when the problem got worse.

Ok, I'll take the plugs back. I had a feeling that they aren't great plugs..

This is NOT a performance reflash. This was the factory Mitsu reflash for rough idle/hesitation above 5000rpm.
