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. It even includes a replacement for the anchored ziptie that keeps the wires in position.
Plug-in replacement for 1994-05 front sensors (including the MSM). Not for 2006 and later cars. 1990-93 models use a single wire sensor.
