Spark Plugs

Car is a supercharged V6, plugs I am currently running are NGK one step colder gapped .038 (stock is .044). I've been having some stumbles with the very occasional misfire at idle. Normal driving and wot seem fine.

Thoughts on pic? Last driving conditions were light on throttle and idle for 30 sec before I shut it off

Less than 5000 miles on plugs.

I would be guessing either the gaping is causing the misfire or you may have a loose connections. I don't know about that brand you are running with, but that could be something too look into.

Opened the gap up a little more and idles better with no spark blow out. I think I'm good for now.
