Wire Sets are constructed out of Moroso ULTRA 40, 7 mm Dia. Ignition Wire with 40 ohms of resistance per foot and have 135 Degree spark plug boots
The black wire sets are sleeved which extends spark plug life and protects against exhaust header heat, chaffing and contaminants
Sleeving also adds extra dielectric strength which is wire’s ability to not to affected by outside electrical pulses
Each wire is terminated with heavy duty, high temperature, easy-pull/positive engagement spark plug boots and on the other end with matching coil boots
