The NGK spark plug wire set for Porsche 911 (1965–1974) uses tinned copper core wiring to meet OE fit and durability expectations for European models, with a high‑temp silicone outer jacket and EPDM/silicone inner insulation for dielectric strength. RFI suppression is incorporated into NGK’s OE-style connectors and metallic resistor boots; glued boots with silicone sealer provide watertight seals. This 6‑wire kit includes a coil lead and limited lifetime warranty.
