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. FAST's XR-1A high-output ignition coil harnesses are pre-made to simplify the XR-1A coils on a Ford Mod or Coyote engine that utilizes FAST XIM ignition control module. The harnesses feature a pair of heavy-duty 30 amp relays and fuses, along with heavy-gauge power and ground lead wire to support the high-current demand of XR-1A coils. They are also designed with extra length to accommodate coils that are mounted on or near the cylinder heads or remote-mounted off the engine.
