Hey guys. I took out my spark plugs yesterday (only one week old) to check them. They had a brownish orange color. Im running JUN III so any acceptable fuel psi is 37-40 psi (according to JUN techs). I know if they were white, they would be lean, and black would be rich. But what about brownish ir orange

 

ralph
you are running that NOS octane boost
thats the reason for the color

 

hey jonas, thanx for the reply. Also i heard that if the plugs are brown, that im running at the right air/fuel mixture
