What It Helps Address

• Misfires caused by worn or damaged ignition wires
• Hard starting related to weak spark transfer
• Rough idle from inconsistent ignition output
• Radio interference from aging suppression components
• Voltage leakage from cracked or deteriorated insulation

Installation Notes and Tips

Verify the vehicle application before installation and route each wire to match the original layout. Inspect spark plugs, coil connections, and wire terminals during service to avoid repeat ignition faults. For best results, replace wires when insulation is brittle, swollen, or visibly damaged, and confirm secure terminal engagement at both ends.
