Moroso Blue Max Spiral Core Plug Wires are engineered for superior performance and they are run through a rigorous testing program, to provide the finest spark plug wires available for the street or strip!Testing shows that by switching aramid fiber wire core to a Kevlar core, the wire tensile strength is increased up to four times stronger, while using less material. The designed Kevlar core is smaller in diameter, with a larger size of the EPDM Layer, for additional dielectric strength. The Blue Max Spiral Core Plug Wires contain a strategically wound, 304 stainless steel alloy conductor that delivers high and even energy spark levels.
