i need to replace my oxygen sensor, and have a couple of questions. ive noticed when looking at things online, they are listed as "upstream" and "except regina". theres even one listed as "Not For Fuel Injection Regina", both of which i do have. what does that mean to me? i have a regina system and need to get the right one. im looking at oreillys because they have the best price. heres the page if anyone wants to see it.

    Hi,

    Upstream sensor is located before the converter, downstream after it. The Regina only uses one upstream sensor. Newer cars nowadays uses sensors before and after the converter for stricter emission control.

    Original sensor for Regina is made by NTK (a subsidiary of NGK). It uses different technology than those made by Bosch. They're incompatible with one another.

    Regards,
    Amarin.
