Spark Plug Wire Set - Motorcraft (WR-4109)
Motorcraft part # WR-4109
High-Dielectric Insulation helps maintain and control voltage delivery while reducing Radio Frequency Interference.
EPDM/Silicone wire jacket, spark plug AND coil / distributor insulators help protect against oil and high temperatures.
Optimized wire lengths help minimize part numbers while still providing proper fit.
Designed for long life - key life durability testing (equivalent to 10 years/150,000 miles) is conducted in addition to on-vehicle durability testing.
Resistance and continuity of each spark plug wire assembly must meet application-specific standards.
Spark plug boots and coil/distributor boots are tested to ensure they maintain the seal with the cable - no dielectric punctures or tracking through the insulator and cable seal.
Terminal ends are designed to ensure they do not pull off the ends of the cable under normal service conditions.
Wires are optimum lengths for easy installation.
Kits use Original Equipment boots and terminals for proper fit.
