Common Issues Addressed

• Misfires caused by worn or heat-damaged plug wires

• Rough idle from deteriorated ignition wire insulation
• Voltage leakage from cracked boots or aging terminals
• Intermittent ignition performance on Ford Escort, Contour, and Mercury Mystique applications

Installation Notes

Match each wire to the correct cylinder routing before removal, and transfer one wire at a time when possible to preserve firing order. Apply the included dielectric grease to the boot interiors where specified during installation. Verify routing away from hot exhaust components and sharp edges, and confirm secure terminal engagement at the spark plug and distributor or coil connection points.
