4 Cylinder massive Spark plug Caddy

A unique design of the massive aircraft spark plug caddy. I will fit any massive plugs (upside down) and also a spot for your anti-seize bottle and gapping gage. The holes are number 1-4 and top and bottom for easy reading and location. Has 1/4" silicone gripper feet so it won't slide of the work bench and recesses for finger holds so it won't slip out of your hand.
