NGK variable pitch resistor cables provide uniform resistance and ensure outstanding electrical conductivity in high-quality cables. Outer EPDM/silicone jacket and inner insulation contain high voltage currents for excellent dielectric strength. NGK variable pitch magnetic core cables produce the necessary impedance to suppress interference throughout the entire frequency spectrum for exceptional 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. 3 Wires (w/Coil Lead)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 9581 spark plug wire set is engineered specifically for Subaru Justy models from 1987 to 1991, providing reliable and efficient ignition performance. These high-quality cables feature a variable pitch resistor design that ensures uniform resistance and excellent electrical conductivity, contributing to optimal engine performance. The outer jacket is constructed with durable EPDM and silicone materials, offering superior dielectric strength and protection against high voltage currents. Inside, the insulation maintains high dielectric properties, reducing the risk of electrical faults and ensuring long-lasting operation.
NGK's magnetic core technology within these cables provides the necessary impedance to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI) across the entire frequency spectrum. This noise suppression results in smoother engine operation and clearer radio reception, making these wires ideal for both daily driving and high-performance applications. The spark plug boots are precisely molded to fit OE or better specifications, ensuring a secure, high-quality connection that resists water ingress thanks to a silicone sealer glued around the boot. The stainless steel terminals utilize up to three serrated crimps, biting into the cable jacket and inner insulation for maximum retention strength. A corrosion-resistant locking C-shaped spring clip guarantees a positive and secure connection to the spark plug, reducing misfires and improving overall ignition reliability.
Designed with ease of installation in mind, this three-wire set includes the coil lead, making it a complete ignition upgrade for compatible Subaru Justy models. Backed by a limited lifetime warranty, these cables provide long-term durability and consistent performance, backed by NGK’s reputation for quality and innovation in automotive ignition components. Whether for routine maintenance or performance enhancement, the NGK spark plug wire set ensures your vehicle runs smoothly, efficiently, and reliably.
