Detailed Description

Delphi XS10242 is engineered as a replacement spark plug wire set for vehicles that need dependable ignition transfer and stable performance under heat and vibration. Delphi builds OE knowledge into its aftermarket ignition parts, and this set reflects that background with composite high-temp wire-wound construction. It is a practical choice for service on applications such as the Chevrolet Astro, Chevrolet Blazer, GMC Safari, GMC Sonoma, and GMC Jimmy, where ignition wire condition can affect starting, idle quality, and overall engine smoothness. This part cross-references DENSO Auto Parts 671-6068 for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from inconsistent ignition delivery
• Engine hesitation during acceleration
• Voltage leakage from aging ignition wire insulation

Installation Notes and Tips

Match each wire to the correct cylinder before removal, then route the new set away from hot exhaust components and moving parts. Inspect spark plugs, distributor cap, and coil connections during service so the ignition system is restored as a complete unit. Confirm vehicle application by year, make, and model before installation. Compatible With 1998-2005 Chevrolet Astro, 1998-2005 Chevrolet Blazer, 1998-2004 Chevrolet S10, 1998-2001 GMC Jimmy, and other listed GM applications.
