40 OHM spark plug wires
The Ultimate in spark plug wire technology, 8mm plus
40 ohms of resistance per foot, which gives the highest spark energy
transfer and the highest EMI/RFI supression. Kevlar® core center with a
nickle copper alloy conductor wire, which is wound 124 times per inch.
This type of center conductor is
a slightly smaller diameter allowing for an increased
amount of premium EPDM insulation material. The use
of Kevlar® produces a core that has four times the
strength of other aramid fiber cores resulting in a very
high tensile strength from a small diameter. the insulated
core is braided with high strength fiberglass strand for
improved resistance to terminal pull off.
The jacket is a high quality silicone product resisting
temperatures up to
600°F. Highest quality silicone spark plug
boots and coil boots. Posi-snap
lock stainless steel spring clip terminals. Dyno-tested, resulting in 2 -
