The NGK spark plug wire set for 1987–1991 Ford Country Squire uses ultra‑low resistance mag‑core wiring to support reliable ignition and reduce EMI/RFI interference. Premium high‑temperature silicone jacket and EPDM/silicone inner insulation with stainless‑steel winding over a ferrite core preserve dielectric strength and lower resistance. OE‑style glued boots, serrated stainless terminals and a locking, corrosion‑resistant spring clip ensure secure, watertight connections; includes two coil leads and limited lifetime warranty.
