NGK ultra-low resistance mag core wire sets provide outstanding performance and durability. High-temp premium silicone outer jacket and inner EPDM/silicone insulation contain high voltage currents for excellent dielectric strength. Stainless steel winding over premium ferrite magnetic core delivers ultra-low resistance, a more powerful spark and excellent EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection. 6 Wires (w/Coil Lead)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 52251 spark plug wire set offers premium performance and durability for a range of Ford and Mercury models from the late 1980s to early 1990s. Constructed with a high-temperature silicone outer jacket and EPDM/silicone inner insulation, these wires effectively contain high voltage currents, providing excellent dielectric strength to ensure reliable ignition performance. The stainless steel winding over a ferrite magnetic core delivers ultra-low resistance, resulting in a more powerful spark and improved engine efficiency. Additionally, the design helps to suppress electromagnetic interference (EMI) and radio frequency interference (RFI), reducing noise that can affect vehicle electronics. The set includes six wires with a coil lead, all designed with OE or better specified spark plug and distributor boots for a precise fit and long-lasting durability. Each spark plug boot is securely glued to the cable with a silicone sealer, ensuring a watertight seal in various driving conditions. Stainless steel terminals with multiple serrated crimps bite into the cable jacket and inner insulation, providing maximum terminal retention strength. The locking C-shaped spring clip, which is corrosion-resistant, guarantees a secure connection between the spark plug and the wire, preventing accidental disconnections during operation. This product comes with a limited lifetime warranty, reflecting NGK’s confidence in its quality and performance. Designed specifically for select 1986-1992 Ford and Mercury models, this wire set is a reliable upgrade to enhance your vehicle’s ignition system. Whether replacing worn-out wires or upgrading for improved engine response, the NGK spark plug wire set ensures optimal performance, durability, and resistance to harsh engine environments.
