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 (w/Coil Lead)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 8143 Spark Plug Wire Set is engineered to deliver reliable performance and efficient electrical conductivity for compatible vehicles such as the Chevrolet Nova and Toyota MR2 from the late 1980s. Designed with high-quality materials, these wires feature an outer EPDM/silicone jacket and inner insulation that effectively contain high voltage currents, providing excellent dielectric strength and resistance to heat and moisture. This construction ensures durability and consistent performance in demanding engine environments. The variable pitch magnetic core within each wire produces the necessary impedance to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) across the entire frequency spectrum. This results in a cleaner ignition signal, improved engine performance, and reduced electrical noise that can interfere with vehicle electronics. The set includes four wires with a coil lead, all fitted with OE or better specified spark plug and distributor boots, which are glued with silicone sealer to ensure a watertight seal and prevent moisture ingress. Stainless steel terminals employ up to three serrated crimps that bite into the cable jacket and inner insulation for maximum terminal retention strength, enhancing reliability over the lifespan of the wires. A locking C-shaped spring clip with corrosion-resistant plating guarantees a secure and positive connection at the spark plug terminal, reducing the risk of accidental disconnection. These wires are backed by a limited lifetime warranty, emphasizing NGK's confidence in their quality and performance.

Designed specifically for a range of 1980s and late-1980s models, this wire set offers a straightforward upgrade to improve ignition system efficiency and engine responsiveness. Whether you're restoring a classic vehicle or maintaining a daily driver, NGK's precision engineering ensures high performance, durability, and resistance to harsh operating conditions. Proper installation of this set can enhance engine idle stability, acceleration, and overall ignition reliability, making it a valuable addition to your vehicle maintenance toolkit. The set is suitable for vehicles that require a 4-wire ignition cable configuration, and it adheres to strict standards for electrical performance and environmental safety, including Prop 65 compliance. Trust NGK for quality spark plug wires that meet or exceed OE specifications and deliver lasting dependability.
