Common Issues This Part May Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition wire insulation
• Voltage leakage from cracked boots or aging terminals
• Loss of ignition performance in older Subaru Standard models

Installation Notes

Verify routing against the original wire layout before removal, and transfer one wire at a time to reduce the chance of cross-firing. Apply the included dielectric grease to the boot interiors where appropriate, and confirm each terminal is fully seated on the spark plug and distributor or coil connection. For Subaru Standard fitment, confirm year-specific ignition routing and connector style before installation.
