ABSTRACT:
The present invention involves a spark plug boot removal tool having a handle portion, an extension portion, and a grasping portion. The handle portion includes a spring-loaded trigger. The grasping portion includes a fixed grasping member and a rotatable grasping member. The extension portion includes an elongated flexible shaft enclosing a control rod that is attached to a triangular block. When the grasping portion is positioned over a spark plug boot, the trigger is compressed, causing the control rod to pull the block, causing the rotatable grasping member to join with the fixed grasping member to clamp around the spark plug boot. Both grasping members have an angular bend that allows the user to position the elongated flexible shaft outside of the engine compartment when exerting a force on the handle portion to remove the spark plug boot, thus minimizing the risk of injury.
