Abstract: In accordance with one embodiment, an ignition coil assembly includes an ignition coil cover, a boot, and an ignition coil. The ignition coil cover includes a plurality of fins, an opening, and a channel. The boot includes a slotted opening and a centralized orifice and is configured to be disposed within the opening of the ignition coil cover. The ignition coil includes a seat and a tab. The ignition coil is configured to be disposed within the centralized orifice. The seat is capable of supporting the ignition coil within the centralized orifice of the boot. The tab is configured to be inserted into the slotted opening and the channel when the ignition coil is disposed within the centralized office and the boot is disposed within the opening.

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.
