NGK spark plug wire set for Mazda Protege (1999–2003) includes two wires (coil lead not required). The variable‑pitch resistor cables provide uniform resistance and dependable conductivity while the EPDM/silicone jacket and inner insulation deliver dielectric strength. Magnetic core construction suppresses EMI/RFI across the spectrum, boots are glued with silicone for watertight seals, stainless terminals use serrated crimps for retention, and a locking C‑clip secures connections. Limited lifetime warranty.
