Good morning kings, just double-checking before I do anything stupid here -

I drive a manual 2004 forester 125 hp.

I got the faulty code P0030, understood as one of the Lambda sensors (oxygen sensors) are faulty. So I ordered this:
FAE Lambdasond it says sensor before catalysator "Universal 77003 ".

And that if I understood correctly should be replaced with this one:

And NOT this one:

Am I good to go? Thanks alot!

Yeah the code P0030 definitely refers to the front air/fuel ratio sensor.
