Vintage Classic Thunder – Old School Looks with Modern Technology

Due to a combination of Kevlar Helically Spiral Wound Core at 350 ohm per foot resistance our cloth plug wire delivers a much greater spark energy, while improving power, idle, and fuel efficiency. Furthermore, Matching Black Silicone Boots, together with Synthetic Jacketing protect against high exhaust temperatures, oil and abrasion. Double Spring Locking Terminals allow for secure, vibration proof connections. Also, Cloth Jacket is rated at 450° F. Most noteworthy, these wires will work on all Harley Davidson® with point or electronic ignitions. Custom fit and universal sets are also available. Universal cloth motorcycle spark plug wires  sets come with black plug boots or rajah terminals. Colors to choose from are: Orange with Black Tracer, Yellow with Black & Red Tracer, Black with Blue Tracer, Red with Black Tracer, and Gray with Brown Tracer.
