    Replacement O2 Sensors: which brand?

    08 Vette. I'm looking to replace the pre-cat sensors. If I'm not mistaken, the OEM sensors are Bosch. I see other brands available, but have not been able to find any relevant information on them to compare to the OE sensors, like voltage switch point or heater performance. Anyone have access to this information?

    Denso
    NGK/NTK
    Walker

    I do not believe the OEM sensors are Bosch...they may be, but I didn't think they were.
