Detailed Description

Walker 924-1446 is a spark plug wire set designed for 1988-1997 Ford truck and van fitments, including 1991-1997 Ford F-350, 1989-1996 Ford E-350 Econoline and E-350 Econoline Club Wagon, 1991-1996 Ford F-250, 1989-1991 Ford E-250 Econoline Club Wagon, and 1988-1990 Ford F-250 and F-350 with EEC IV. This part cross-references DENSO Auto Parts (e.g., 671-8089) for the same application. The wire set uses OE-style silicone insulation and stainless steel terminals to support stable ignition transfer and long-term service in heat-exposed engine bays.

Common Issues Addressed

• Misfire caused by worn or heat-damaged plug wires
• Hard starting related to weak spark delivery
• Rough idle from deteriorated ignition wire insulation
• Voltage leakage at boots, terminals, or wire ends
• Ignition performance loss on high-mileage Ford F-250, Ford F-350, and E-350 models

Installation Notes

Verify engine configuration and EEC IV application before ordering, especially on 1988-1990 Ford F-250 and F-350 models. Route each lead to match the original layout, seat the boots fully on the plugs and distributor or coil connections, and apply the included dielectric grease where appropriate to help protect terminal contact points.
