Kwiksen 234-9028 Air Fuel Ratio Oxygen Sensor Upstream Right Replacement

Installed it, and the check engine light was back within 10 days. You get what you pay for I guess.So after complaining, I got a replacement sent to me, and guess what?.... It is already tripping the same code on the car. Do yourself a big favor, and just save up for the real thing. You'll waste more time dealing with the problem than actually fixing it. The only thing this "brand" would be good for, is if you have a code and need to pass emissions, or if your were trading in or selling your car. Pure junk!

new catalytic converter and all new o2 sensors lasted 4 days and check engine lick back on

Terrible product. Stopped working a few months in. Kwiksen will give you the run around when you want to use the 1 year warranty. Just spend the extra $$$ and buy Denso. That’s what I ended up doing.

Did what it said it would do.Great price.

They are good sensors are recommended

I have 2001 Toyota RAV4 153000 miles, this was for Upstream Left (Driver side). Every thing was good. Hopefully it will last +70K miles. Thanks

Work just as well as OEM at half the cost. Great value, easy to install, if you can get the old one off. If you don't have an offset socket, do yourself a favor and get the right tools for this job.

Stopped working on day four. This is a complete joke.
