Honda VX Oxygen Sensor for CA
 

Maybe this has been answered already, but I have been noticing online that the 4-wire O2 sensor for California VX's can run as little as $75-100 compared to the $300-375 price of the non-California VX sensors. While I am in CA and need the 4-wire, is this discrepancy accurate? I've noticed that NTK has a good price on what I need, while Bosch runs at $120. Is the quality of these aftermarkets comparable to Honda OEM? Thanks a bunch- Mike
