Ford E8PZ-12259-A Cable Set

If you want to keep spark plug wires in excellent condition, always replace them when you change spark plugs. While the engine is running, just check for arcs or sparks in a well-ventilated garage. Start checking and labeling them one by one from the number one cylinder. Pull out the rubber boot by twisting it off or use a removal tool to separate wires from spark plugs. Attach the cables again tightly; pliers should be used where required. Clean off any dirt on these wire and examine them for burns, cracks or damages. Take off wires from the distributor, inspect for corrosion, and also replace any broken ones. This may involve putting in place new distributor cap and rotor, looking out for cracks, carbon tracks, worn terminals and corrosion. Apply silicon dielectric compound on single point rotors tip and replace cap and rotor when defects are found on them.
