What's this exactly? Under cowling

Ok so I was looking around at stuff today and noticed a honeycomb type thing under the windshield cowling. What exactly is it?

Um… that is a nest for/of paper wasps/hornets!!!

I kinda thought it looked kinda nest-y, however the “tubes” look to be metal

Ok so I got the answer on the other jag forum! Apparently I have one of the, not often actually seen factory pollen filters! I am willing to bet it’s absolutely oem and has never been changed! Maybe why my AC doesn’t seem great?

Aha!!! Your second photo shows it more clearly…whew!!!
