I regularly clean and reoil my K&N ICE air filter.

    There appears to be a secondary filter in the housing lid and I have never touched it. Is it replaceable or cleanable?

    It's a charcoal filter to prevent gas fumes from going the other direction. No maintenance required.

    Makes sense, thanks a lot - one less worry, not that I have many Prius related worries.

    Hi Ozark, how do you like the K&N filter? Notice any improvements in fuel savings or performance? Seems like a controversial subject here and on other forums but the majority who use this particular filter seem to be quite satisfied...

    I like it. I installed it at the first oil change and clean it about every 25,000 miles. The Prius seems to have a little more power and may get a bit better mileage but those may be my imagination since I had only 5K miles when it was installed and now have 144K. My main advise is that a clean filter is best. K&N is not "install and forget", it requires a modest amount of maintenance.
