First time replacing spark plugs. Stock to Rutheniums gapped at 0.024".

I have no idea how to assess how these plugs are. What do you guys think? 2.5k miles on them. Tuned at 1k miles, stage1.

Do they still? I thought there new stg 1 recommendation was Rutheniums in stock heat range?
Only thing I've seen from them-
"If you are utilizing the stock turbocharger system, a “one step colder” plug such as the NGK Racing R7437-8 (gap to .024”) is recommended over OEM. RS7 plugs are also acceptable for stage 1/2 cars (gap to .024”)."

Do what you like. I stand by my assessment.

My understanding is they updated the info on their Facebook group, but not on the site. 1 step colder has been causing detonation issues with some stg 1 cars.

Like Diggs said, do what you want with your car.

I have the ngk racing plugs at 1 step colder with a stage 1 tune and I haven't had any noticeable issues on the AP. I figure I'd check them at 10k miles, about 5k to go, and if they look bad I'll think about going back to stock. My concern is that I just do a lot of driving that only lasts about 10-12 minutes, so with my short drives and the colder plugs I'm not sure things are getting as warm as they should. The only thing I've noticed so far is I get a ton of misfires at start up if I try to drive my car before the RPMs calm down. Ed made that sound normal and that I should just wait until the RPMs fall before I start driving, but I never had this problem with either of my other cars I tuned. Now I'm kinda thinking that might be the colder plugs. I haven't seen anyone else with this complaint though.
