The whole air system in the Yaris is great. I recently left my car sitting for a while, and a chipmunk made a nest with the cabin air filter material. I looked under the glove box, unscrewed three Phillips head screws to drop the blower, cleaned it all out and screwed it back in. No messing around with body panels or other parts that were in the way, no custom or odd-size connectors. A mechanically simple system, easy to access and maintain.
