The NGK spark plug wire set for Mercedes‑Benz 300SEL (1970–1971) uses tinned copper core wiring to deliver OE-fit durability, combined with a high‑temp silicone outer jacket and EPDM/silicone inner insulation for strong dielectric protection. RFI suppression is located close to the source in NGK’s connectors and metallic resistor boots; glued boots with silicone sealer provide watertight seals.
