The NGK spark plug wire set for 1989–1992 Ford Ranger uses ultra‑low resistance mag‑core construction to support consistent spark energy and minimize EMI/RFI noise. High‑temperature silicone outer jacket with EPDM/silicone inner insulation and stainless‑steel winding over a ferrite core preserve dielectric strength and reduce resistance. OE‑specified glued boots, serrated stainless terminals and a locking spring clip deliver secure, watertight connections; coil lead not routed and limited lifetime warranty.
