There used to be an engineer who tested oil filters and it was quite revealing, but he has stopped so the info is a bit dated, but interesting:
Here is my inquiry today and the response from the company selling the pink filters (I spared the writer including his name):
You're kidding right? All STi parts are expensive in general. How do you
justify an STi $200 shift knob, etc. Not to be rude, but if these parts seem
to expensive, you should simply choose some other parts...
