I have an 86 GT hatchback, 5.0, 5 speed, headers, cam, GT40 intake, nitrous setup, Ford motorsport wires (blue), and lord knows what else in the motor (this is the way I bought it), it currently has NGK UV45 plugs, not sure what I should replace them with (same if available? something else that may be better and/or available).

Thanks for any advise.
