NGK ultra-low resistance mag core wire sets provide outstanding performance and durability. High-temp premium silicone outer jacket and inner EPDM/silicone insulation contain high voltage currents for excellent dielectric strength. Stainless steel winding over premium ferrite magnetic core delivers ultra-low resistance, a more powerful spark and excellent EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection. 8 Wires (w/Coil Lead)

The NGK Part 53423 Spark Plug Wire Set is engineered for optimal performance and durability in a range of classic Jeep models, including the Jeep Gladiator, Jeep CJ5, and Jeep CJ7 from various years. Designed with high-quality materials, this wire set features an ultra-low resistance magnetic core that delivers a more powerful spark, ensuring efficient engine performance and smooth operation. The high-temp premium silicone outer jacket combined with EPDM and silicone inner insulation provides excellent dielectric strength and resistance to heat, oil, and chemicals, safeguarding high-voltage currents during engine operation.
Each wire incorporates stainless steel winding over a premium ferrite magnetic core, which not only minimizes resistance but also offers superior EMI/RFI noise suppression, resulting in cleaner engine signals and improved electromagnetic compatibility. The spark plug and distributor boots are constructed with OE or better specifications, offering a precise fit and long-lasting durability. The boots are securely glued with silicone sealer to ensure a watertight seal, preventing moisture ingress that could compromise performance.
The stainless steel terminals utilize up to three serrated crimps that firmly bite into the cable jacket and inner insulation, providing maximum terminal retention strength. A locking C-shaped spring clip with corrosion-resistant plating guarantees a secure, positive connection to the spark plug, reducing misfires and ensuring consistent engine ignition. This set includes eight wires with a coil lead, making it suitable for a variety of classic Jeep applications from the late 1950s through the early 1980s. Backed by a limited lifetime warranty, the NGK Spark Plug Wire Set offers reliable, long-term performance for enthusiasts and professionals alike.
