Oxygen sensor replacement
My 2005 6MT needs both front and rear O2 sensors. Research on the net showed that Mazda quotes 2 different part numbers (with significantly different prices ; eg $304-front, $129-rear).
I have found several aftermarket dealers offering replacement 4 -wire sensors (NGK) which are identical for both the front and rear. The price quoted is much less than the original Mazda parts. (sample site - http://www.sparkplugs.com/results_app.asp). Does anyone know if these sensors will work with no cutting or other mods, and why are they identical when Mazda uses 2 different sensors? |
The front sensor is a wideband sensor and the rear sensor is a narrowband sensor. They aren't the same and the front is more expensive.
You should be able to get better pricing though. Can't see the sensors on your link. |
O2 replacement sensor
Thanks for the info. Here is another site which claims that this sensor will work for both front and rear (and costs only $122.39).
I think I'll play it safe and go with the Mazda original.
