NGK Chrysler 300 1971-1965 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 deliver a more powerful spark to your engine, which can make a noticeable difference in how smoothly it runs. They're built with a high-temperature silicone outer jacket and EPDM/silicone inner insulation to handle high voltage currents effectively, ensuring excellent dielectric strength. This set fits a wide range of classic Chrysler, Dodge, and Plymouth vehicles from the mid-60s to early-70s, including models like the Chrysler 300, Dodge Charger, and Plymouth Barracuda.

NGK specifies OE or better for the spark plug and distributor boots, meaning they're made to fit precisely and perform reliably. The spark plug boots are securely glued to the NGK cable with a silicone sealer, creating a watertight seal to keep moisture out. For terminal retention, stainless steel terminals use up to three serrated crimps that bite into the cable jacket and inner insulation, providing a strong connection. The spark plug terminal connection is secured with a locking C-shaped spring clip that has corrosion-resistant plating for a positive connection.
