Replaced your spark plugs but still have a misfire? You might need new 1979-1993 Mustang spark plug wires. 5.0 Resto's replacement and performance spark plug wires are the perfect addition for any engine. Installing new wires can help with a rough idle caused by faulty wires. Pick up a set of blue, black, red, or yellow wires from Ford Racing to give your engine a custom look. It is important to keep your wires separated and out of the way of hot components to prevent them from being damaged. Pick up a set of wire separators to keep them neatly tucked away.
These wire kits fit 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, and 1993 Fox Body Mustangs.
