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. 8 Wires (w/Coil Lead)
