Smart coils are an excellent choice for ignition on high compression / high boost race cars, but have very specific power and grounding requirements to hit their full spark potential. Our complete harness kit allows for just that with a simple plug-and-play installation. Our smart coil wiring kit is also one of the cleanest, best-finished and most inclusive kits available.
