Product Details

This spark plug wire set is designed for ignition systems that require reliable secondary ignition performance and consistent electrical transfer. Walker 924-1003 is a fitment-based replacement for 1985-1992 Chevrolet Sprint, 1985-1988 Pontiac Firefly, and 1985-1988 Suzuki Forsa.

This part cross-references DENSO Auto Parts (e.g., 671-3001) for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak secondary ignition output
• Intermittent ignition performance from cracked boots or degraded insulation
• Voltage leakage at the wire ends or terminals
• Service replacement for aging ignition wire sets on compact import vehicles

Installation Notes

Match each wire to the correct cylinder routing before removal, and transfer one lead at a time to preserve firing order. Clean the terminal areas, apply the included dielectric grease where specified, and confirm each boot seats fully on the spark plug and distributor or coil connection. Verify routing away from hot exhaust components and moving parts.
