The Edelbrock #22746 ignition coil is a high-output, oil-filled cannister-style coil with a 0.7 ohm primary resistance recommended for Pro-Flo 4 EFI systems and compatible with many aftermarket EFI and ready-to-run distributors. Its higher winding ratio increases voltage build-up and spark energy versus lower-winding coils, while the oil-filled design helps protect windings from vibration for reliable ignition under demanding conditions.
