• Hard starting related to weak ignition transfer
• Intermittent engine hesitation under load
• Voltage leakage from cracked or deteriorated insulation
• Poor terminal connection at the spark plug boot

Installation Notes and Tips

Verify the vehicle application before installation and route each wire to match the original ignition layout. Keep the wires separated from exhaust heat sources and sharp edges, and confirm each silicone boot seats fully on the spark plug and ignition coil terminals. For 1999-2005 Buick LeSabre and Park Avenue, 1999-2005 Pontiac Bonneville, 1999 Oldsmobile 88 and LSS, and 2006 Buick Lucerne applications, match the wire routing to the factory configuration for proper operation.
