What It Helps Address

• Misfires caused by worn or heat-damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition output
• Voltage leakage from cracked or deteriorated wire insulation
• Intermittent engine performance issues tied to poor terminal contact

Installation Notes

Verify wire routing against the original layout before removal, and transfer one lead at a time to preserve cylinder order. Confirm the spark plug end uses the female terminal style and the distributor or coil end uses the male terminal style before installation. Check boot seating at each connection point and inspect nearby ignition components for wear that could affect performance.
