Review on Walker Products 350 34258 Oxygen Sensor by Curtis Sherman

I have used so many oxygen sensors on my car from big name Denso to Bosh. And for my life, the only one who stands out and never goes out is Walker! I don't know what they have on these things because it seems like there must be a computer chip or something because I was having trouble turning off all the sensors except this one. My lights always go out on cold starts, but there's no problem with my catalytic converter. I don't really want to talk too fast but Walker will be my next visit, if my car needs something Walker is for I understand. It seems to me that this is an old school American product. I love it.
