Product Details

NGK Spark Plug Wire Set 51079 is part of NGK’s ignition product line, which includes spark plugs, glow plugs, ignition coils, coil-on-plug boots, and wire sets. NGK applies its long-standing OE-focused manufacturing experience to replacement ignition components for domestic and import vehicles. This wire set is built as a specific application part rather than a universal set, which helps ensure the correct routing and fitment for the listed Buick, Chevrolet, Oldsmobile, and Pontiac models.

This part cross-references DENSO Auto Parts 671-6051 and Delphi XS10238 for the same application.

Common Issues This Part Addresses

• Misfires caused by worn or damaged spark plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition wire insulation
• Electrical noise affecting ignition system operation
• Loss of engine performance from increased wire resistance

Installation Notes and Tips

Verify routing against the original wire layout before installation and match each lead to the correct cylinder. Inspect spark plugs, coil terminals, and boots at the same time so the new wire set is not installed over worn ignition components. Confirm fitment by year, make, and model before ordering.
