Abstract

An ignition coil engages an inner surface of a bore of an engine, the providing access to a spark plug. The engagement is a boltless cam-lock engagement. A spring is associated with the engagement to hold the assembly in tension, and the spring also contacts a ground terminal in the ignition coil and the base of the spark plug to provide a short electrical path for radiofrequency interference (RFI) dissipation.
