    You haven't removed those?

    After around 3k miles I looked at the filter in question.
    Its surface area is far larger than the fresh air inlet. That said, it blocks a considerable amount of light, and blowing across it proves it is not transparent to airflow.
    Will removing it make much difference? Nope. Did I anyway? Yep.
    I record every fill up, so over the next few I will do some averages and show any difference to be within a margin of error. Do I care? No, I voted Trump so I MUST hate the environment.

    I put a K&N rechargeable air filter in my Crosstrek. I figured with all the discussion about people 'over oiling' their filters the carbon filter would just be a failsafe to protect the MAF sensor......

    I believe this filter does nothing for performance or the environment, just another money grabbing maintenance item. If it causes problems ($130 US for a new one ) I will just throw it in the trash.

    Once I removed the carbon pad, the car actually wanted to glide (coast). That's the best way I can describe it.
    Yes, this, its a subtle thing, but significant. Also seems to transition gears better,
    Specially low gears. (5mt)
