A common problem with servicing spark plugs is carbon accumulation in the jug threads. Cleaning these threads regularly can save big money by preventing thread damage and the need to pull the jug and install thread inserts. This special designed tool works very well to limit this problem.

It provides maximum depth penetration and its unique spring action assures that there will be no enlargement of the existing thread pitch diameter.
