I think I am gonna to replace my oxy sensors (2) on my car after 120K Km.
Have read this article on the page of oxygensensors.com
I have passed the emission test 6 months ago, but I guess I can reduce the fuel consumption and also even the smoothness of running much more.
How often should I change them?
Your vehicle manufacturer recommends a specific mileage at which your oxygen sensor(s) should be changed. However, contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

Why should I change my oxygen sensors?
A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture...enabling virtually complete combustion to take place. By providing closed-loop control of the mixture, it becomes possible to use three-way catalytic converters to achieve the maximum reduction in exhaust gas emissions.
Here in Japan they cost more than double the price in US.
Anyone has experience with the Walker? They are cheaper than the Bosch.
Do not want to buy a universal one, prefer the one with the right plug
