Default Tell me about my spark plugs...

07 STi, 4,500 miles, stage 1 OTS map since 1,100, Stage 2 OTS map since 2,500ish. I pulled the plugs to swap with one step colder in anticipation of my protune this week. Thoughts?

Look just about perfect to me. No aluminum pits or chips, no oil fouling, no overburned white spots, no red coloration from weird fuel additives, no physical impacts. Look like good plugs to me.

Absolutely. Switching to a colder plug is a mistake for this tune.

You should not be going 1 step colder on the stock turbo, its not nearly enough to justify that, if anything it could do more harm than good.

Looks good but keep the stock heat range.
