Inexpensive time saver
Thought they would break or not fit properly, but they stood up and did the job! Really handy to have this tool makes life there alot easier.
Works perfectly!
I used this tool to carefully chase out the oxygen sensor hole on my exhaust manifold to repair the damage done by the previous mechanic forgetting to use the thread grease that comes with sensor.
Exactly what I needed.
I recommend you buy one of these before starting your O2 sensor swap. It is cheap insurance to avoid damaging your new sensors. Run this in and out before I stalking the new ones to avoid fouling the threads.
