Im changing my plugs today. For two step colder plugs. Which are for the nitrous. But I want some kind of picture chart for spark plugs. If anyone know where one is online or if you have one. Please upload it. Another thing, these plugs are over due for a change. I should have changed them last summer when I also dod knew spark plug wires. SplitFire wires to FMS. But I didn't. . .

Description of plug number one: It seem kinda red. On the over laping wire. It is red on top but black inside.The tip is black but under that is red. Now this isn't red "red." Its a darker type of red almost brownish.

I hope these help..... :Beer
