NGK No Applications Spark Plug Wire Set

What you get in this NGK 58004 wire set is a complete package for upgrading the ignition system on many common 4, 6, and 8 cylinder vintage engines. Inside the box, you'll find cut-to-fit spark plug wire leads, straight spark plug boots, and 90-degree distributor boots. It also comes with stainless steel terminals and nipples, plus an installation kit with instructions to help you get everything connected properly.

These wires are built with a high-quality carbon core cable, similar to NGK's direct-fit sets. The outer jacket is made of high-temperature, premium silicone, while the inner insulation uses EPDM and silicone to handle high voltage currents and provide excellent dielectric strength. This construction helps ensure low resistance and effective EMI/RFI noise suppression thanks to the carbon suppression core. The spark plug boots are securely attached to the NGK cable using a silicone sealer, creating a watertight seal to keep moisture out.
