2006 Mazda3 2.3 O2 Sensor

[NCoppersmith]

I'm trying to replace the front O2 sensor on my brothers Mazda3 and am having a heck of a time trying to get the part I need. It's the 2.3L model and has a 5 wire O2 sensor harness. Most of the sensors I can find that look like they'll fit are like $400 bucks a pop. Is that correct? That seems like an obscene amount for an o2 sensor. Anyone have a lead on a good place/price to look at? I've tried thepartsbin.com and rockauto.com but any part that looks like it'll fit (which is nothing like the service manual by the way, which only shows a 4 pin part) is in the wideband tuner O2 sensor price range.

Yeah, we saw that. Was hoping it was cheaper than that...bought a Replacement part that was supposedly and OEM direct fit for the car from thepartsbin and the harness was nowhere near what the car used.
