What Our Customers Are Saying:

“MUST have when changing O2 sensors. People, the right tools for the right job!!!! I cannot stress this enough. Slipped over the 02 sensor and wires, turn the ratchet (with breaker bar), done! I changed out my primary and secondary O2 sensors. No issues, no hassles, no busted knuckles, no nothing!"

"This little gem is a knuckle saver for replacing O2 sensors on a V6 Toyota. Worked like a charm (all I had to do was show it to the car and the O2 sensors backed themselves out!!!) Well not quite - but it made the job doable for this do-It-yourselfer."

"I'm not a gear head and prefer others work on my car. But a recent move to a new city and a very tight budget forced me to do more than I'd normally like. Where we live requires cars to pass an emission test - that hasn't been an issue in the past. Well the day before I had scheduled the test my diagnostic light came on. The test facility told me it was the O2 sensor - they could repair it for $X or he said it was a fairly easy repair to do myself. He even showed me where the sensor was on the engine and what I'd need to do the work."
