NGK Ford Country Squire 1991-1987 Spark Plug Wire Set

When you're replacing the spark plug wires on your Ford Country Squire, Lincoln Town Car, or Mercury Grand Marquis, you want a set that's built to last and deliver a strong spark. This NGK wire set includes all the necessary wires, with OE-specified spark plug and distributor boots designed to fit right and maintain a watertight seal thanks to silicone sealer. The stainless steel terminals use multiple serrated crimps to ensure they bite into the cable jacket and insulation, giving you the best possible terminal retention strength.

Inside, you'll find an ultra-low resistance magnetic core wrapped in stainless steel. This design helps deliver a more powerful spark to your plugs, which can lead to improved engine performance and better fuel efficiency. The high-temperature silicone outer jacket and EPDM/silicone inner insulation work together to contain high voltage currents, providing excellent dielectric strength and durability. Plus, the locking C-shaped spring clip on the spark plug terminals ensures a secure connection that resists corrosion.
