Delphi XS10268 Spark Plug Wire Set

Delphi XS10268 Spark Plug Wire Set

Delphi XS10268 is a spark plug wire set built for ignition service on select classic Chevrolet and GMC applications. It combines composite high-temperature construction with Delphi’s OE-focused engineering background to support consistent spark delivery in older ignition systems.

Key Features

• Composite high-temperature wire construction for demanding underhood conditions
• OE heritage informed by Delphi’s experience supplying top automakers
• Includes spark plug wire set and instruction sheet
• Direct replacement option for select Chevrolet Corvette, Blazer, Impala, and GMC Jimmy applications
• Part number XS10268 for catalog and service matching

Application Details

Compatible with 1966-1974 Chevrolet Corvette, 1970-1972 Chevrolet Blazer, and 1971-1972 GMC Jimmy, along with additional classic Chevrolet and GMC truck and van applications listed in the fitment data. This Delphi spark plug wire set is also a cross-reference for NGK 51434 and Continental 50084 for the same application.

Delphi builds this ignition wire set using knowledge developed through decades of OE supply experience. The result is a service part aimed at restoring stable ignition performance on vehicles such as Chevrolet Corvette, Chevrolet Impala, and GMC Jimmy where reliable wire insulation and consistent routing matter.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition wire insulation
• Voltage leakage in older ignition systems
• Service replacement for cracked or aged wire sets

Installation Notes and Tips

Use the included instruction sheet during installation and route each lead to match the original layout. Confirm the vehicle is listed in the fitment data before ordering, especially for 1975-1976 Chevrolet and GMC models noted as without High Energy Ignition (HEI). Inspect distributor cap, plugs, and coil connections at the same time to avoid repeat ignition issues.

Quality Assurance

Delphi draws on 100 years of OE experience and supplier knowledge from work with major automakers, and that heritage is reflected in the design approach behind XS10268. The composite high-temperature construction supports dependable service in classic ignition applications.
