NGK Dodge Raider 1989 Spark Plug Wire Set

The variable pitch resistor in these NGK spark plug wire sets is key to getting consistent resistance and outstanding electrical conductivity. This matters because it helps ensure each cylinder gets the right spark, which is crucial for smooth engine operation and reliable performance. They're built with an outer EPDM/silicone jacket and inner insulation that can handle high voltage currents, giving them excellent dielectric strength to keep that spark where it needs to be.

NGK uses a variable pitch magnetic core in these cables, which helps suppress radio interference (EMI/RFI noise) across the entire frequency range. You get a solid connection at the spark plug thanks to boots that are glued with silicone sealer for a watertight seal, and stainless steel terminals with up to three serrated crimps that bite into the cable for strong retention. The spark plug boots are designed to fit right, ensuring good performance and durability.
