Abstract: The present invention is a reinforced connection between a distributor body and a distributor cap. The distributor cap rests on the distributor body as in the conventional arrangements. However, an additional clamp is provided to mount over the interface between the distributor cap and distributor sandwiching the components there between. A screw/bolt passes through the clamp and through both the cap and distributor body and engages a threaded portion of the clamp. By simply tightening the screw/bolt, the cap and distributor are clamped together without inducing concentrated stresses in the distributor body. The clamp may be used in a retrofit application to strengthen the existing connection between the cap and distributor body, repair the connection in a cracked or otherwise damaged distributor, or installed as part of an original equipment design.

Abstract: A distributor cap adaptor that secures an after market distributor cap adaptor to a distributor. The distributor distributes high voltages to spark plugs in an internal combustion engine. The after market distributor cap having a terminal distance diameter that is 15% greater than a conventional distributor cap. The connection of the after market distributor cap to a body of the distributor cap adaptor provides an improved insulation value that substantially eliminates ignition cross fire in the internal combustion engine.
