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. 6 Wires (w/Coil Lead)

The NGK Chevrolet Astro 1991-1986 Spark Plug Wire Set offers exceptional performance and durability for your vehicle's ignition system. Crafted with ultra-low resistance magnetic core wires, this set ensures a powerful, consistent spark that enhances engine efficiency and responsiveness. The high-temperature premium silicone outer jacket combined with EPDM and silicone insulation provides excellent dielectric strength, containing high voltage currents effectively and reducing electrical interference. This construction minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), promoting cleaner engine operation and reduced noise.
The stainless steel winding over the ferrite magnetic core further reduces resistance, delivering more energy to each spark while maintaining high durability. The OE or better specified spark plug and distributor boots included in this set guarantee a precise fit, ensuring reliable performance and long-lasting service life. Each spark plug boot is glued to the cable with a silicone sealer, creating a waterproof seal that prevents moisture ingress and corrosion. The stainless steel terminals utilize up to three serrated crimps that securely bite into the cable jacket and inner insulation, ensuring maximum terminal retention strength under demanding engine conditions. Additionally, the locking C-shaped spring clip with corrosion-resistant plating provides a secure connection to the spark plug, maintaining consistent contact over time.
This six-wire set, including the coil lead, is designed to fit specific models such as the 1987 GMC V1500, Chevrolet V10, GMC R1500, and Chevrolet R10 from 1986 to 1987, offering a direct replacement for OEM components. It is backed by a limited lifetime warranty, emphasizing NGK’s confidence in its quality and durability. Suitable for automotive applications, this set is ideal for restoring or upgrading your vehicle’s ignition system to ensure optimal performance and reliability. Proper installation and high-quality materials make this wire set an excellent choice for both professional mechanics and DIY enthusiasts seeking long-lasting, high-performance ignition wiring solutions.
