This is Garage Sale priced because it is a factory shipped item that we do not carry in house.
This dual-gauge leakdown tester measures the condition of your head gaskets, piston rings, and valves. The gauge records incoming air pressure, and the right gauge records individual cylinder pressure - and the difference is you leakdown. Includes 14mm spark plug adapter.
