NGK Infiniti M30 Spark Plug Wire Set Part Number 9973 – High-Performance Automotive Ignition Cables

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 (w/Coil Lead)

Upgrade your vehicle's ignition system with the NGK Infiniti M30 Spark Plug Wire Set, Part Number 9973, designed to deliver reliable performance and durable construction. These high-quality wires feature a variable pitch resistor cable design that offers uniform resistance and exceptional electrical conductivity, ensuring efficient spark delivery and consistent engine performance. The outer EPDM/silicone jacket combined with inner insulation provides superior dielectric strength, effectively containing high voltage currents to prevent electrical leaks and enhance durability.
NGK's magnetic core cables produce the necessary impedance to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) across the entire spectrum of engine frequencies, reducing noise and improving overall signal clarity. The set includes six wires with a coil lead, tailored to fit specific Nissan and Infiniti models from 1986 through 1992, including the Nissan Maxima and Infiniti M30.
Each spark plug boot is designed to meet or exceed original equipment specifications, glued securely to the cable with a silicone sealer to ensure a watertight seal and prevent moisture ingress. Stainless steel terminals utilize up to three serrated crimps that bite into the cable jacket and inner insulation, providing maximum terminal retention strength for a reliable connection. The locking C-shaped spring clip, plated with corrosion-resistant material, guarantees a secure and positive attachment to the spark plug, reducing misfires and maintaining optimal engine performance.
This wire set is covered by a limited lifetime warranty, ensuring long-term satisfaction and dependability. Its robust construction and precise fit make it an excellent choice for restoring or upgrading your vehicle's ignition system, delivering consistent sparks for smooth engine operation and enhanced efficiency.
