The NGK spark plug wire set for Mercedes‑Benz 280 (1973–1976) uses a tinned copper core for OE-fit durability on European applications, with high‑temp silicone outer jacket and EPDM/silicone inner insulation for strong dielectric protection. RFI suppression is integrated into NGK’s OE-style connectors and metallic resistor boots; boots are glued for a watertight seal.
