Abstract:
A distributor cap adaptor to secure an after market distributor cap to a distributor that distributes voltages to spark plugs in an internal combustion engine, the after market distributor cap having an outer diameter and a terminal distance diameter, the terminal distance diameter is approximately 15% greater than a conventional distributor cap, comprising:a substantially cylindrical body providing a base and a top, the body having an outer diameter that decreases relative to an outer diameter of the base in a radial direction toward a central axis to a minimum outer diameter point and increases from the minimum outer diameter point to the top, the body being affixed to the distributor at the base; and a distributor cap register disposed above the top of the body, an outer diameter of the distributor cap adaptor being larger than the outer diameter of the after market distributor cap to receive and connect the after market distributor cap to the body, wherein the connection of the after market distributor cap to the body of the distributor cap adaptor results in an improved insulation value that substantially eliminates the cause of ignition cross fire in the internal combustion engine.
