NGK ultra-low resistance mag core wire sets provide outstanding performance and durability. High-temp premium silicone outer jacket and inner EPDM/silicone insulation contain high voltage currents for excellent dielectric strength. Stainless steel winding over premium ferrite magnetic core delivers ultra-low resistance, a more powerful spark and excellent EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection. 12 Wires (w/2 Coil Leads)

LIMITED LIFETIME WARRANTY: See package for details

The NGK Part 54193 spark plug wire set is designed to deliver exceptional performance and durability for Jaguar XJS models from 1989 to 1991. Constructed with a high-temperature premium silicone outer jacket and inner EPDM/silicone insulation, these wires effectively contain high voltage currents while providing excellent dielectric strength. The stainless steel winding wrapped over a premium ferrite magnetic core ensures ultra-low resistance, resulting in a more powerful spark that enhances engine efficiency and performance. Additionally, the wires are engineered to minimize electromagnetic interference (EMI) and radio frequency interference (RFI), promoting cleaner signals and smoother engine operation. The set includes 12 wires with two coil leads, ensuring comprehensive coverage for your vehicle's ignition system.
