Detailed Description

Delphi XS10392 is engineered for ignition wire replacement on compatible GM vehicles, including 1999-2008 Pontiac Grand Prix, 2000-2005 Chevrolet Impala, 2000-2005 Chevrolet Monte Carlo, 1999-2004 Buick Regal, 2005-2009 Buick LaCrosse, and 2008 Buick Lucerne. The composite high-temperature material helps the wire set withstand underhood heat while supporting stable spark transfer from the ignition system to the plugs. Delphi’s OE background is reflected in the fit, materials, and service-focused design of this replacement part.

This part cross-references NGK 51031 and Carlson 7696 for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition output
• Loss of acceleration response tied to ignition wire deterioration
• Voltage leakage from aging insulation in high-heat conditions

Installation Notes and Tips

Match each wire to the correct cylinder before removal, then replace one lead at a time to preserve firing order. Inspect boots, coil connections, and spark plugs during service, and route the wires away from hot or moving components. Confirm fitment by year, make, and model before installation; this part is listed for N/A position applications.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed over 100 years of working with major automakers. That background supports consistent materials selection and application-specific fitment for ignition service.
