Overview

The Motorcraft WR-5934 is a set of eight spark plug wires designed for specific Ford and Lincoln models. These wires feature EPDM/Silicone construction with high-dielectric insulation to control voltage delivery and reduce radio frequency interference. The insulators help protect against oil and high temperatures, and the optimized wire lengths are intended for easy installation.
Show original supplier description
The Motorcraft WR-5934 spark plug wire set provides OE fit and function, engineered to strict Ford standards. Each wire in the set features an 8.0 mm wire size with a 5000 Ohm resistance per foot, designed to deliver optimal voltage while minimizing radio frequency interference. The EPDM/Silicone wire jacket, along with spark plug and coil/distributor insulators, offers robust protection against oil contamination and high engine temperatures, ensuring durability and reliable performance. Motorcraft conducts key life durability testing equivalent to 10 years or 150,000 miles, in addition to on-vehicle durability testing, to ensure longevity. These components are manufactured to strict Ford Engineering standards and are backed by Motorcraft's Service Parts Warranty. Fitment for this WR-5934 set includes select 1996-2000 Ford Crown Victoria and 1997-1999 Ford F-150 models equipped with the 4.6L V8 engine. It is important to verify fitment for your specific vehicle's year, make, model, and engine size, as assistance may be required for specific applications, such as distinguishing between 4.6L and 5.4L V8 engines. This wire set does not include ignition coils. For optimal vehicle enhancement, it is recommended to replace both ignition coils and spark plug wires if experiencing misfires.
