Why not upgrade them while performing a necessary repair

they are the backbone of the Japanese OEM and high performance world

Oxygen Sensors Rotor * OE fitmentO2 sensors not only go bad, they typically become less reactive long before they fail. The RX 7 does not alert you of an out of tolerance O2 sensor. On 1984 88 models, there is not even a check engine light to tell you that sensors have failed. The consequences of a substandard oxygen sensor are poor fuel economy and a lack of smoothness at cruise. With an RX 8, the check engine light will stay on and may prevent you from passing a smog test. *
