I can laugh about it now, but I was sure ticked when I pulled the Unifilter from my Scotty II air filter housing for cleaning, to find that after not driving the truck for a week a rodent had used 30% of the filter foam to build a nest in the filter housing.
To prevent future occurances, I screened both inlets.
Those of you out there with Scotty systems might want to take a look if you live where the onset of winter sends furry little pest' looking for shelter.
It's not likely, but I hope the perpetrator was sucked into the turbo compressor blades, along with the other debris that was.

I didn't see any fur on the blades

I had this happen on my 3rd gen truck! Now I read it.
