A nice heavy duty Coil for the 616-720 Tractors. This coil is shorter than the OEM Coil which is actually a benefit! When this Coil is slid down in the OEM bracket, a lot of the body of the Coil isn't exposed to the hot cylinder head right in front of it. No Coil overheating due to the underhood temps these Tractors can produce with the Onan CCKA & CCKB engines.  This kit comes with our weathertite #10 eyelets on each end on a new Ignition box circuit protected with our cotton woven tar/fiberloom covering to keep heat off the circuitry. This particular Coil is for spark plug boot type spark plug wires. Does not have provision for screw type boots as OEM. Can be used with our 1703-31 or 1703-32 Spark plug wire sets. For use with OEM Coil use 1703-29 or 1703-30 wire sets.
