quick oxygen sensor question

[roofusgooner]

There are two oxygen sensors in the front of our cars, right? Are they the same physical part number or is there a left and a right part number? Thanks.

There is a Left and a Right Sensor.

If you Buy Plug & Play Sensors There Different Part Numbers, Other wise you can just buy two Standard 1 Wire O2 Sensors and Splice them on the factory Plugs

what about this pre-cat front and rear business I'm seeing on oxygensensors.com https://www.automedicsupply.com/catalog.php?&pkey=1167027&application=Non-Calif+ESV

no rear sensor just two located on the manifold

So I should just get two of the one labeled for the front?

different manufacturers show left and right numbers or just one.
Walker shows the same part number for left and right. so just order two of 250-21009
