mazda pisses me off sometimes...

why is the rear oxygen sensor more expensive than the front? aren't they essentially the same?

www.oxygensors.com lists both for $49.00 USD... now i understand that these are universal replacement sensors, but they come with the OEM style connector so it's an easy replacement (if you can get to the rear one). but mazda wants about $240.00 CDN for the rear sensor where the front is about $180 something... why is this? :confused:

has anyone bought from www.oxygensensors.com before?

thanks,

im guessing since the rear O2 sensor has a longer wire harness its more expensive.. i just changed mines and thats the only difference i can see... maybe also since its located on the 2nd bank it may be a little more pricey... these are just hypothesis'... correct me if im wrong.. peas
