Abstract
A shock absorbing assembly reduces impact forces on a terminal of a spark plug that is mounted within a spark plug bore of an internal combustion engine when a pencil ignition coil is mounted thereto. The shock absorbing assembly includes a plug cup that is fixedly secured to the terminal end of the spark plug. A case cup is movably mounted to the plug cup. The case cup includes a resistor receptacle for receiving an end of a resistor therein. The shock absorbing assembly also includes a cup spring that extends between the plug cup and the case cup. The cup spring absorbs the impact forces of mounting the pencil ignition coil to the terminal of the spark plug.
