Common Problems This Part Can Help Address

• Misfires caused by worn or heat-damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from deteriorated wire insulation or terminal wear
• Intermittent ignition performance from loose or aging wire connections
• Service replacement for cracked, brittle, or oil-contaminated plug wires

Installation Notes and Tips

Verify engine-specific routing before removal and replace one wire at a time when possible to preserve firing order. Confirm the female terminal ends seat fully at the spark plug and distributor/coil connection points, and inspect nearby ignition components for wear before installation. For best results, route the wires away from exhaust heat and sharp edges.
