Yeah originally was getting NGK but on FCP they were back ordered as they are everywhere.
I did a post asking if I really needed 1 step colder and people reassured me no. I even ran a E30 e85 mix map and no missfires or anything. All good.
So idk if step colder plugs are really needed on factory turbos... I don't want to spread misinformation but this is what I seem to notice.
