Testing shows that, by switching aramid fiber wire core to a Kevlar core, the wire tensile strength is increased to be 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. Fits 1987, 1988, 1989, 1990, 1991, 1992 Chevy Truck.
