Has not failed me yet, unlike much of the reviews that I hear for other aftermarket options in the same industry. I did much research before choosing a vendor and I'm very thankful that this product is legitimate. My car recognizes even that the catalytic converter that I have is probably aftermarket, and not non-functioning or malfunctioning O2 sensors. The price range was good.

For being a product on Amazon, it seems to be doing its job the way they said it would. If you're looking for an O2sensor then here, you go. They work great.

i purchased this based on the good “stars-report” but it did not work: getting error code. the vw original on the car was still good, but having to replace to up-stream sensor, i thought to be wiser and replacing the down-stream sensor also: not problem with 10 yr/old sensor, problem with this new one. Bad luck?

Good Product and fixed with slight modification.

Not sure at this time. Did not fix issue, need to look further to see if there are other issues.

Is not compatible with Audi still have code for oxygen sensor the mechanic said I have to get OEM part

Instalé este sensor de oxígeno en mi carro y funcionó perfecto desde el primer momento. El motor se siente más estable, desapareció la luz de ‘check engine’ y el consumo de combustible mejoró un poco.

It is good quality, and they replaced me quickly when I had problems with the unit
