    8.65mm 90 Degree Boots Spark Plugs Race Wire Set.

    The most powerful & EMI/FRI resistant ignition wire available for racing today!

    These are assembled, black, 8.65mm spiral core wires with 90 degree silicone boots that can take up to 600 degrees.  HEI distributor, locking stainless steel plug terminals, coil wire is included, conductor is Copper/Nickel.  KEVLAR core four times stronger than Aramid cores.  40 Ohms of resistance per foot, tightly woven fiberglass silicone-impregnated insulation provides up to 8,000 extra volts of protection.

    Ultra 40 un-sleeved wires are a cost effective version of the Ultra 40 Race Wire without heat sleeving. Wires feature a Kevlar core, four times stronger than other aramid fiber cores, that increases the tensile strength of the wire while reducing its center diameter. This allows for the surrounding insulation to be thicker, resulting in greater dielectric strength.
