NGK Ford Country Squire 1991-1990 Spark Plug Wire Set

The stainless steel winding over a premium ferrite magnetic core in these NGK wire sets is key to their ultra-low resistance. This design helps ensure that a strong, consistent spark makes it to your spark plugs, which is crucial for efficient combustion in your 1990-1991 Ford Country Squire. If your old wires are showing signs of wear, like misfires or rough idling, a fresh set of NGK wires can make a noticeable difference in how your engine runs.

NGK builds these wires with a high-temperature silicone outer jacket and an inner EPDM/silicone insulation layer. This combination is designed to handle the high voltage currents needed for a powerful spark while also providing excellent dielectric strength to prevent energy loss. The spark plug and distributor boots are made to meet or exceed original equipment specifications, ensuring they fit snugly and create a watertight seal with the cable, thanks to a silicone sealer. You'll also find that the stainless steel terminals use multiple serrated crimps to bite firmly into the cable, providing strong terminal retention, and a locking spring clip ensures a secure connection to the spark plug.
