摘要： Pre-cut spark plugs with trimmed L-shaped electrodes are used in the racing industry for engines that are fueled by racing fuels such as high octane racing fuels and/or nitrous oxide or nitro methane, thus keeping the engine from detonating prematurely. However these spark plugs are expensive. Disclosed herein is a jig that trims the end of a standard commercial spark plug's L-shaped-electrode. The jig has a body and a finger screw that secures the spark plug body while exposing the L-shaped electrode. The spark plug is secured in the jig, and the jig secured in a vise so that a user may manually employ a saw such as a hacksaw to trim the end of the L-shaped electrode at a precise distance from the electrode's end that match the pre-cut spark plug's trimmed L-shaped electrode. This saves the user considerable expense.
