The FAST XR-1A High-Output ignition coil set is built for very high-horsepower LS applications including high-compression, boosted, or nitrous engines. The coils deliver spark energy comparable to CDI systems without requiring an ignitor module, supporting high current and voltage demands for engines beyond OEM coil capabilities. They work with OEM wiring and FAST coil-near-plug products for coil-per-cylinder installations.
