Abstract: Distributor caps, for example high energy ignition (HEI) distributor caps, may be configured to eliminate spark plug wire overlap via implementation of internal rewiring, for example rewiring corresponding to a firing order of a particular V-style engine. Individual tower terminals may be coupled to internal segments such that consecutive internal segments are coupled to consecutive tower terminals in the firing order, all tower terminals associated with cylinders on one side of the V-style engine are located on one side of the distributor cap, and all tower terminals associated with cylinders on the other side of the V-style engine are located on the other side of the distributor cap.
