Works
The length of the sensor was slightly longer than the OEM it replaced making for a bit more fiddling to get it to sit properly. Outside of that it works.

Is this any actual brand? I see the more expensive one is a Walker but what brand is this sensor?

BEST ANSWER: We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please don't hesitate to ask.
Is this for California emissions or federal?

BEST ANSWER: If this is replacing an original part on your car, and that car is legal in California, I cannot see how it wouldnt be legal.
