Not needed, but if I had upgraded my turbos and was pushing over 30psi of boost I would definitely gap down to .018, but with my stock turbos at 24.5psi of boost it is not needed.
Zero issues with gap. I Was just curious if anyone knew what these Black marks were.
I read it may be normal and the black mark is where the fuel/air ratio mixture is entering the cylinder and hitting that spot on the plug.
