The original factory spark plugs in the 1996-2004 GT, Mach 1 and Cobra applications listed below were platinum plugs, however, the copper plugs in this kit will fit and work great as a suitable replacement. Be advised that copper and nickel plugs will have a shorter service interval than the platinum plugs.
