Abstract
According to one example, a spark plug gapping tool includes a first side handle, a second side handle, a middle handle, and a pusher that are made of a non-metallic material. The middle handle is positioned in-between the first side handle and the second side handle, and has a stopper surface and an insert slot that can receive a feeler gauge insert. The pusher is rotatably positioned in-between the first side handle and the second side handle, and has a hollow housing that can receive a terminal end of a spark plug. In operation, a distal end of the middle handle and distal ends of the side handles can move closer together, when a proximal end of the middle handle and proximal ends of the side handles are moved closer together by a user's hand, so as to gap the spark plug.
