The FAST™ XR-1A LS-Style High-Output Ignition Coil Set is designed specifically for high-compression naturally aspirated, boosted or nitrous-equipped applications making more than 1,000 horsepower. This horsepower range is far beyond the capabilities of OEM coils. The spark energy of the FAST™ coils is comparable to CDI (capacitive discharge ignition) systems without the need to convert. The Smart Coil design also requires no ignitor module. The FAST™ XR-1A LS-Style High-Output Ignition Coil Set delivers up to 44,000 volts, 103mJ of energy, and supports a maximum of 19 amps of current and 17 volts. It is designed to work with all OEM equipment, as well as FAST™ products that support coil-near-plug applications such as the XIM™ and EZ-LS™ ignition controllers.
