Crane Cams FireWire Spark Plug Wires
The most important function of a spark plug wire is to transfer the maximum amount of energy to the plugs, and ultra low resistance, 25 OHM, FireWire does this in spades. What's more, its reactive core construction effectively filters out RFI and EMI "noise" generated by today's high-output ignition systems. This protects on-board computers, instruments and helps preserve audio clarity. FireWire's 8.5mm pure silicone double-layer construction resists the effects of high underhood temperatures and insulation breakdown caused by abrasion. Pure silicone boots are rated to 550 degrees (F). It's designed for use on tube-steel header equipped engines. FireWire is available in custom sets for many popular applications, or in "universal" sets with straight, 135° and 90° boots for 4, 6 and 8-cylinder engines.
Up to 50% more spark energy! FireWire's low per-foot
resistance transmits up to 50% more energy to the spark
plugs than other "performance" suppression core wires.
