Sizing & Fit

XR-1A High Output Ignition Coils from FAST are great for Ford racers, as the factory option is not ideal for engines with high cylinder pressures. However, these aftermarket coils can be difficult to wire thanks to the complexities of the Ford engine. The new XR-1A High-Output Ignition Coil Harness is pre-made to simplify the XR-1A coils on a Ford Mod or Coyote engine that utilizes FAST XIM ignition control module. The harness features a pair of fuses and relays, along with heavy gauge wire to support the high current demand of XR-1A coils. It is also designed with extra length to accommodate coils that are mounted on or near the cylinder heads or remote-mounted off the engine.
