Plug-in four-wire rear oxygen sensor for 1996-00

Our replacement O2 sensor is different than most aftermarket ones because it has a Mazda connector on the end. This means a super-easy installation, just unplug your old one and plug the new one in. Just like installing a factory sensor but without the price tag or the hassle of splicing in a generic aftermarket part.
