Detailed Description

Walker 924-1397 is a spark plug wire set engineered for older Ford truck and car platforms, including 1977-1990 Ford F-100, F-150, F-250, F-350, Bronco, LTD, Thunderbird, E-250 Econoline Club Wagon, and E-350 Econoline applications, plus select Lincoln Continental and Versailles and Mercury Cougar, Grand Marquis, Marquis, and Monarch models. It uses OE-style silicone insulation and stainless steel terminals to support stable ignition transfer and durable connection points in demanding underhood conditions.

This part cross-references DENSO Auto Parts (e.g., 671-8076, 671-8081) for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak ignition transfer
• Intermittent spark loss from cracked boots or degraded insulation
• Voltage leakage at aging wire terminals
• Rough idle and reduced throttle response from inconsistent spark delivery

Installation Notes and Tips

Verify engine and ignition system compatibility before installation, especially on 1988-1990 Ford F-250 and F-350 models that exclude vehicles with EEC IV, and on 1988 Ford E-350 Econoline models with EEC IV. Route each wire to match the original layout, keep wires separated where possible, and apply the supplied dielectric grease at the boots for improved sealing and serviceability.
