Backed by the Motorcraft Service Parts Warranty which offers 2 years, unlimited mileage, limited labor cost and no commercial exceptions. Warranty is supported nationwide by Ford/Lincoln dealers and Ford Authorized Distributors. 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. Motorcraft Spark Plug Wires are manufactured with premium-quality materials to strict Ford Engineering standards to help maintain AND control high voltage delivery to spark plugs.
