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. 6 Wires (Coil Lead N/R)

The NGK Part 8158 spark plug wire set is engineered to deliver reliable performance in a range of late 20th-century Mazda and Ford vehicles. Designed with high-quality variable pitch resistor cables, these wires provide uniform resistance along their length to ensure consistent electrical conductivity and optimal engine performance. The outer EPDM and silicone jacket, combined with inner insulation, effectively contain high voltage currents, offering excellent dielectric strength and durability under demanding conditions. These features contribute to a more stable ignition system and help prevent electrical interference that can impact engine operation.

NGK's magnetic core cables produce the necessary impedance across a broad spectrum of frequencies, which significantly suppresses electromagnetic interference (EMI) and radio frequency interference (RFI). This noise suppression results in a cleaner electrical environment, minimizing potential disruptions to sensitive electronic components in your vehicle. The spark plug boots are made to OE or higher standards, ensuring a precise fit, superior performance, and long-lasting durability. Sealed with silicone sealer, the boots form a watertight connection, protecting against moisture and corrosion.

Each cable terminates with stainless steel terminals that utilize up to three serrated crimps, biting into the cable jacket and insulation for maximum retention strength. The locking C-shaped spring clip, plated to resist corrosion, guarantees a secure connection to the spark plug, reducing misfires and improving engine efficiency. This set includes six wires compatible with specific Mazda and Ford models from the early 1990s, making it an essential upgrade for maintaining or restoring engine performance. Backed by a limited lifetime warranty, the NGK spark plug wire set offers dependable quality and peace of mind for automotive enthusiasts and professionals alike.
