A pre-combustion chamber is adapted to be installed in the spark plug well of an existing engine. The spark plug is removed and a centering mandrel is installed in the ln1 spark plug hole. Tools are placed on the mandrel for modifying the walls of the spark plug well to accommodate the pre-combustion chamber assembly. Once the well is modified, the tools and mandrel are removed and the pre-combustion chamber is installed in the well in place of the original spark plug.
