Review: Passed maryland emissions 09 prius. - 09 prius with 387,000 miles. Worked as it should. Passed maryland emissions with a new cat also. Took minutes to install o2 sensor. Had code p0420.
Review: Great part for a great price - Great part for a great price compared to what was wanted at my local auto parts store. I am already seeing an improvement in my MPG. It's too early to tell how much it has really impacted things but prior to putting this on I had 38 MPG and now my prius shows around 43. Overall it was fairly easy to replace. I didn't expect the wire harness is up inside the cabin of the car but a quick view on YouTube showed me how to get the job done in under 30 minutes.

09 prius with 387,000 miles. Worked as it should. Passed maryland emissions with a new cat also. Took minutes to install o2 sensor. Had code p0420.

### ⭐⭐⭐⭐⭐ Great part for a great price
*by C***N on November 29, 2022*

Great part for a great price compared to what was wanted at my local auto parts store. I am already seeing an improvement in my MPG. It's too early to tell how much it has really impacted things but prior to putting this on I had 38 MPG and now my prius shows around 43. Overall it was fairly easy to replace.

### ⭐⭐⭐⭐⭐ Worked on my Prius, knock-off did not
*by M***M on July 13, 2025*

Had a check engine light after replacing my stolen cat. Used a cheaper o2 sensor, kicked off codes forever until replaced. Swapped it with this. Still getting codes, but they are due to the replacement cat being garbage. It is doing g it's job! Probably woukd have saved the cat with the proper sensor
