Detailed Description

This Delphi spark plug wire set is engineered for vehicles that need dependable spark delivery and heat resistance in the ignition system. It is a strong match for long-tail searches such as spark plug wire set for 1977 Buick Regal, 1980 Oldsmobile Cutlass, or 1986 Chevrolet Caprice ignition wire replacement. The XS10201 part number is also referenced in OE-style replacement searches for Buick LeSabre, Oldsmobile Delta 88, and Pontiac Firebird applications.

Delphi draws on more than a century of OE experience, and that background is reflected in the materials and fitment focus of this ignition wire set. The composite high-temp design helps the wires stand up to elevated engine bay temperatures while maintaining the routing and connection requirements expected in classic passenger cars.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak ignition transfer
• Rough idle from inconsistent spark delivery
• Voltage leakage from aging insulation
• Service replacement on aging ignition systems

Installation Notes and Tips

Use the included instruction sheet to match the original routing and terminal locations before removal. Verify plug wire length, end style, and cylinder routing against the vehicle’s original setup, especially on applications with 90-degree and straight-end configurations noted in fitment. Confirm compatibility for your exact year, make, and model before installation.
