Overview

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.

The thread cleanout tool is for 18mm threads only.

Reviews

This one works. I bought the cheaper one, it worked, I lost it. I know. I bought another cheaper one, it cross-threaded the spark plugs threads, which Im pretty sure is a bug, not a feature. So I sprang the extra $20 and got this, and it works perfectly. Im sure theres a lesson in there somewhere, but I will probably never learn it. See the research of Dunning-Kruger. I tremendously enjoy the breath-taking view from Mt Stupid.

Easy to use, worked as described. Nice tool to have to clean out old anti-seize build up
