are they normal or what.. i don't know how to tell if i'm running to rich or to lean or whatever.... how am I suppost to know of they are still good or the plugs are bad.. they are ZEX turbo/nos plugs.. thanks..

 

that looks normal. You dont want it to be excessively clean that means its too lean. If its just black everywhere and dry its fuel. If its black and wet its oil. If it has shinny bits of aluminum its detonation. Its time to change them, use NGK bkr7e if you need a turbo\plug.

 

how much timming ?

 

they were in my car for almost a year... zex turbo/nos plugs were 3 prong plugs.. . don't know my timming..

 

They look pretty good, but one of them looks like it almost has a green tint to it. Wait a second, just kidding...
