Your cart is empty.The back-tap's patented collapsible design allows it to engage be placed through the spark plug hole and into the chamber. A mandrel is then drawn back, expanding the tool's threaded area and threading into the clean threads at the bottom of the spark plug hole. The Backtap repairs the damaged threads as it is drawn up through the spark plug hole, bringing debris and metal filings with it. Made in USA and comes with a lifetime warranty.

The tool is made with soft metel and the threads were damaged with one use.

Wasn't sure how this would work after reading some of the reviews but wow were they wrong. Do as the instructions say and it worked fantastic. Saved me hundreds over paying the dealer to repair the stripped out o2 sensor port. Even if it never worked again which I don't believe, it is Well worth the money.

Worked like a charm and saved me a few hundred dollars, I cross threaded the first few threads when I tried to to use a thread restorer Because of the restricted hole location, my mechanic wanted to remove the manifold to re re-tap the hole properly.To make sure the tap started straight, I inserted a wooden dowel in the hole and noted the dowel's orientation and then I started the tap as close to this position as possible. So as not to start the tap cross threaded, I inserted the tap so that it's top thread was a few threads below the top and slowly expanded it while gently rocking. It was obvious when the tap engaged properly. I expanded the tap and turned it back and forth. I repeated this, expanding the tap a little at at a time on each try until I needed pliers to expand any further. Then I ran the tap out. After that the oxygen sensor was easy to install.

This saved me $$$. My old 02 sensor bung was stripped out and I could not get a thread chaser to go in straight. I don't think this tool will stand up in the long run, but it was cost effective as a disposable anyway.
