The NGK spark plug wire set for Jaguar XJ12 (1973–1979) delivers ultra-low-resistance performance using stainless steel winding over a ferrite magnetic core to boost spark energy and suppress EMI/RFI. A high‑temp silicone outer jacket and EPDM/silicone inner insulation protect against voltage leakage; glued boots with silicone sealer create a watertight joint and serrated stainless terminals provide strong retention. This kit includes 12 wires with coil lead and limited lifetime warranty.
