Common Uses

• Replacing cracked or heat-damaged ignition wires
• Restoring spark transfer on aging Ford, Lincoln, and Mercury engines
• Addressing misfire complaints tied to worn wire insulation
• Correcting rough idle caused by weak or inconsistent ignition output
• Servicing vehicles with original-style ignition wire routing and terminal requirements

Installation Notes

Match each wire to the original routing before removal, and transfer one lead at a time to reduce the chance of cross-connection. Use the supplied dielectric grease on the boots where specified, and confirm each terminal is fully seated on the spark plug and distributor or coil connection. Verify engine-specific fitment for the listed non-California and EEC IV applications before installation.
