This patent describes an ignition distributor cap to work with a rotor. The rotor has a cylindrical member having an upper and lower portion, each portion having a bore where a rotor ring surrounds the upper portion of the cylindrical member thereby forming an annular channel, spark plug electrodes, a coil electrode, a shaft, a bowl shaped housing and a rotor electrode in an ignition distributor for an internal combustion engine with cylinders. The ignition distributor cap comprises: a generally domed shape with a generally hollow interior and with a circular shaped bottom to mate with the bowl shaped housing; spark towers equal in number to the number of cylinders of the internal combustion engine, projecting up from the top of the dome shape and slotted to accept spark plug electrodes and allow them to protrude into the distributor cap interior for communication with the rotor electrode; a vent tower projecting up from the top of the dome shape and provided with a vent port through to the distributor cap interior to allow for the outward flow of the atmosphere inside the distributor cap and bowl shaped housing; a coil tower projecting up from the top of the dome shape and slotted to accept a coil electrode and allow it to protrude into the distributor cap interior for communication with the rotor electrode; and interruption ribs which radially follow the dome shape, protruding into the hollow interior of the dome shape.
