A spark plug removal tool apparatus and method for a spark plug having components of an extended smooth spark arc producing terminal portion, an adjacent helical threaded portion, an adjacent hex drive, an adjacent insulator portion, and a terminal electrical interface extension. The tool apparatus includes a non rotating collet extension having a plurality of fingers to removably engage the electrical interface and an inner surrounding sidewall that threadably engages the collet, also an outer surrounding sidewall rotatably engaged to the inner surrounding sidewall not having one-way axial movement as between the inner and outer surrounding sidewalls, wherein the collet, inner, and outer surrounding sidewalls are all co-axial. Operationally, when the tool starts to unscrew the spark plug from an engine head, an axial non-rotating force is applied to the electrical interface extension that helps prevent separating damage between the spark plug components.
