Our Racing DUI Coil Kit is designed for high revving engines that spin more than 7000 rpm’s. This coil is capable of 10,000 rpm’s, that is almost twice the output of a stock HEI coil! The Racing Coil comes installed in a brass terminal cap and includes the rotor and nylon rotor hold down screws. With the higher voltage output, spark plug gaps can be opened up to .055″. The wider plug gaps will allow more spark energy into the combustion chamber providing a better burn of the fuel mixture for increased horsepower. The Racing Coil Kits fit all GM V8, 6 cylinder and 4 cylinder HEI/DUI distributors.
Racing Coil Kits have a 30 day warranty from date of purchase.
