Universal wire set. Straight spark plug boot. The most powerful and RFI/EMI resistant ignition wire available for racing today – bar none! From dual-mag Fuelers and high-compression Comp Cars, to the demands of Nextel Cup Racing, Moroso Ultra 40 establishes a new standard for ignition wire performance that has the competition scrambling to catch up!
At 8.65mm and 40ohms of resistance per foot, Moroso Ultra 40 Race Wire incorporates a spiral wound nickel/copper alloy conductor wrapped at the optimum ratio to produce the highest level of spark energy while producing the lowest level of electromagnetic and radio frequency interference.
Moroso's new Kevlar® core, four times stronger than other aramid fiber cores, allows them to increase the tensile strength of the wire while reducing its center diameter. Moroso is then able to increase the surrounding insulation, resulting in greater dielectric strength.
This combination has produced the ultimate ignition wire for any race combination you have!
