NGK Mazda R100 Spark Plug Wire Set Part Number 8172 – High-Performance Ignition Cables for Mazda RX Series

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/2 Coil Leads)

The NGK Mazda R100 Spark Plug Wire Set Part Number 8172 is designed to deliver reliable and efficient ignition performance for a range of Mazda models including RX-7 and RX-2 series from the early 1970s through the late 1980s. Crafted with high-quality materials, these cables feature a durable outer EPDM/silicone jacket and inner insulation that contain high voltage currents, providing excellent dielectric strength and resistance to heat and environmental factors. This construction ensures consistent electrical conductivity and long-lasting performance under demanding engine conditions.
The variable pitch magnetic core technology incorporated in these cables produces the necessary impedance throughout the entire frequency spectrum, which effectively suppresses electromagnetic interference (EMI) and radio frequency interference (RFI). This results in cleaner ignition signals, smoother engine operation, and improved overall performance. Designed to meet or exceed OE specifications, the spark plug boots are glued to the cables with a silicone sealer, creating a watertight seal that prevents moisture ingress and ensures durability in wet conditions.
Stainless steel terminals with up to three serrated crimps securely bite into the cable jacket and inner insulation, providing maximum terminal retention strength for reliable electrical connections. The locking C-shaped spring clip, plated for corrosion resistance, guarantees a secure and positive connection to the spark plugs. This set includes four wires with two coil leads, making it a comprehensive solution for compatible Mazda RX models. Backed by a limited lifetime warranty, the NGK Mazda R100 Spark Plug Wire Set offers exceptional value, durability, and performance for enthusiasts and professional mechanics alike. It is suitable for installation in vehicles from 1970 to 1985 and is a critical component for maintaining optimal ignition system function.
