The NGK spark plug wire set for Mazda R100 (1970–1972) is a 4‑wire kit with two coil leads, made to restore proper ignition routing and limit electrical interference. Variable‑pitch resistor cables provide uniform resistance and reliable conductivity; EPDM/silicone jackets and inner insulation deliver dielectric strength. Magnetic core design suppresses EMI/RFI, boots are silicone‑sealed for a watertight seal, and stainless terminals use serrated crimps with a locking C‑clip. Limited lifetime warranty included.
