• Hard starting related to weak spark delivery
• Ignition noise that can interfere with electrical systems
• Rough idle from deteriorated wire insulation
• Voltage leakage from aging plug wires

Installation Notes and Tips

Verify engine application and wire routing before installation. Match each lead to the correct cylinder location and inspect boots, terminals, and coil connections for wear or corrosion. For best results, replace wires when insulation is cracked, swollen, or heat-damaged, and keep the routing away from hot exhaust components and sharp edges.
