At least I'm not the only one to find pieces of a bird and feathers in mine. Was playing on the highway, WOT and met a bird trying to fly across the highway... poor thing.

I just pulled the whole box, installed a open cone filter, and hosed off the box and put into storage.

Oddest thing before that was a butterfly when I first got the car and did a change out/maintenance check(air/fuel filter, plugs, wires, oil/filter, belts, coolant, etc...). Spread out perfectly across the filter, looked amazing, but kind of odd at the same time.
