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. 4 Wires (Coil Lead N/R)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 9993 Spark Plug Wire Set is engineered to deliver reliable high-performance ignition system connectivity for your Chevrolet Nova from 1985 to 1988. Crafted with high-quality materials, these wires feature a durable EPDM/silicone outer jacket and internal insulation that effectively contain high voltage currents, providing excellent dielectric strength and insulation. The variable pitch resistor cables ensure uniform resistance throughout the set, resulting in consistent electrical conductivity and optimal engine performance.
Each wire incorporates NGK's magnetic core technology, which produces the necessary impedance to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) across the entire frequency spectrum. This suppression helps minimize engine noise and enhances overall electrical system stability. The spark plug boots are designed to meet or exceed OE specifications, ensuring a precise fit, robust performance, and long-lasting durability. The boots are securely glued to the cables with silicone sealer, creating a watertight seal that protects against moisture and environmental contaminants.
Stainless steel terminals utilize up to three serrated crimps to firmly bite into the cable jacket and internal insulation, providing the highest terminal retention strength possible. Additionally, a corrosion-resistant locking C-shaped spring clip ensures a secure, positive connection to the spark plug, reducing the risk of accidental disconnection during operation. This set includes four wires, making it suitable for your vehicle's coil lead connections. Backed by a limited lifetime warranty, the NGK Spark Plug Wire Set offers peace of mind alongside premium quality. Designed for easy installation and long-term reliability, this wire set is a vital upgrade for maintaining your engine's ignition efficiency and overall performance.
