Good fit and performance
Perfect fot for my 01 Lexus rx300. I noticed an immediate difference, and I have zero complaints. Definitely recommended.

Exact replacement
My 2003 Toyota Highlander with 180,000 miles finally killed one of the O2 sensors and rather than spend $150+ for a name brand one, I figured this would work fine. Turned out to be the case. Side by side they almost look the same and the CEL turned off as soon as the sensor was replaced.Great value and functionality.

Fixed my problem
The product was perfectly made just like the original one. I know because I’m a ASE Parts Specialist. When you’re changing an O2 sensor they are not all made the same and it make you believe that it may not be the right part even though it may work out. This product is identical, worked, and cleared my engine light. I needed 2 installed them and after waiting a a year to ensure they didn’t come right back on like some cheap parts will do, I’m still happy with your product! ThankYou!

You get what you pay for - Updated
I wanted to update: the company reached out to me and made the issue right, unprompted. I may have had a bad part but I would do business with them again.Original: Couldn't afford an OEM sensor at the time. Worked for about 6 months before the light came back. Went with an OEM sensor.

Shorted after 3 months
The title said it all. After 90 days of installation, the sensor shorted and now my car is displaying p01150 code.I did reach out for warranty service and the seller did replace with a new one. Luckily, I can replace it myself.
