The tool was incredibly easy to use and help me diagnose an exhaust blockage in my 1997 toyota camry. It allowed me confirm my suspicious but simply removing the front o2 sensor ans plugging in the provided nipple and then just run the car. It was so easy and clear I was able to diagnose the issue in minutes. ... show more

This device feels quality for the price and works well. Saved me hundreds on replacing the cat and muffler for my exhaust, since this tool indicated they were actually good afterall.

    • WORKS
Style: Exhaust Back Pressure Tester
packed properly, fast delivery, decent product. The only possible issue is the rubber o-ring sealing the connection to the exhaust. I tested starting cold and not sure if o-ring would survive on an exhaust at full operating temperature.

    • Great tool to have in the tool box
Style: Exhaust Back Pressure Tester
I have this for almost a year now and used this pressure tester a few times on a few different cars and it works great and had not had any issues with it. It fit in Honda and Toyota really well. Have not try it on any other brands but I am sure it will work just fine.

The media could not be loaded. Worked as it should. Unscrew the O2 sensor and plugged in and was easy to do. Helped me narrow down the my cars rough running condition. Transmission was shifting at the wrong times, engine had no power and was bogging, and idle was weird. Found out it was a clogged cat and now the car drives great. ... show more

    • Works and was low cost
Style: Exhaust Back Pressure Tester
Every so often you roll the dice on the cheapest tool you can find because you're only buying it for one specific task. This fit the bill. I wanted to test to see if I had an exhaust restriction and with this attached to where the 02 sensor normally is, I was able to easily do so.
