NGK American Motors Ambassador 1963-1958 Spark Plug Wire Set

NGK uses a stainless steel winding over a premium ferrite magnetic core in these wire sets, which helps achieve ultra-low resistance. This means you get a more powerful spark to the plugs, which can make a noticeable difference in how your engine runs. They’re built with a high-temperature silicone outer jacket and EPDM/silicone inner insulation to handle the high voltage currents safely and effectively.

The spark plug and distributor boots are designed to fit just like the original equipment, ensuring a solid connection and good performance. NGK glues the spark plug boots to the cable with a silicone sealer for a watertight seal, and the stainless steel terminals use multiple serrated crimps to bite into the cable jacket and insulation, giving you strong terminal retention. The locking C-shaped spring clip on the spark plug terminal also ensures a secure connection.

This wire set fits a wide range of American Motors and Jeep vehicles, including models like the Ambassador, Gremlin, and CJ7. It’s a well-built option for anyone looking to replace their old, worn-out spark plug wires.
