    Default New here, O2 sensor topic

    Hello guys.
    I have gone through few mazda 3s
    Every single one of then needed upstream o2 sensor.
    Best price I got was $160ish with my discounts.
    Has anyone found a supplier for cheaper ones?

    I bought an aftermarket one some 190k ago off Rock Auto and haven't had an issue.....I know some say always stay Genuine parts when it comes to O2 sensors.

    you don't have to buy genuine (aka OEM), but if you bought OES, it's nearly the same thing... either Denso or NGK (NTK) aftermarket will be just fine... they're OES

    If i am not mistaken... OEM O2 is made by NGK.
    At 220K maybe i should look at 2 new O2's
    Get them on sale online over the holidays perhaps
