Common Problems This Part Can Address

• Misfires caused by worn or heat-damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from deteriorated wire insulation or boot wear
• Intermittent ignition performance from loose or aging terminal connections
• Voltage leakage across cracked or contaminated wire insulation

Installation Notes

Verify engine layout, coil/module configuration, and wire routing before removal. Match each lead to the original routing path to avoid crossfire or incorrect firing order. Inspect spark plugs, distributor or coil terminals, and nearby heat sources during installation, since damaged ignition components can shorten wire life. Confirm fitment against the vehicle notes, including Magnavox Module applications on select 1992 Buick, Oldsmobile, and Pontiac models.
