The NGK spark plug wire set for Mercedes‑Benz 250 (1968–1970) uses tinned copper core wiring selected for European applications, with a high‑temp silicone outer jacket and EPDM/silicone inner insulation to contain high voltage and preserve dielectric strength. Integrated RFI suppression in NGK’s connectors and metallic resistor boots reduces interference; glued boots with silicone sealer ensure watertight connections. This 6‑wire kit includes a coil lead and limited lifetime warranty.
