ABSTRACT:
An ignition system of an engine has a coil which is spaced away from a spark plug to protect the coil from heat of a combustion chamber and combustion gas leakage. The electrical connections between the coil and spark plug of current design practice have not performed satisfactorily due to loosening of connections, absorption of energy within the connectors and the escape of electrical energy. The present ignition extender overcomes these shortcomings by resiliently biasing the extender between the source of high energy and the spark plug to provide a positive and reliable electrical connection therebetween. Further, the extender is of a relatively rigid construction so as to prevent bending and the problems that can result therefrom. When included in an engine, the extender is combined with a shield to further protect and increase the functional life of the components
