Moroso new Ultra 40 Race ignition wire sets are the most powerful and RFI/EMI-resistant wires available for racing today. Features of these 8.65mm wires include a Kevlar® core that's four times stronger than Aramid cores, a class-leading 40 ohms of resistance per foot, nickel copper alloy conductors for superior spark energy transfer, an extra-thick EPDM layer for greater dielectric strength, high-temperature silicone boots that can withstand heat up to 600 degrees, and locking stainless steel plug terminals. Plus, their closely woven fiberglass, silicone-impregnated insulation provides up to 8,000 extra volts of protection, and their extra-thick diameter extends wire life by adding additional insulation against heat, chaffing, and contaminants.
