I was uder the hood the other day and found this all wadded up in my engine valley. It looked like a mouse nest when I found it. The third pic is where it came from...it's the stuffing/sound protection from the front left fender near the air filter. The strange thing is that the truck hasn't been parked for any period of time at all recently...very strange. I don't know what the heck is going on in my engine compartment??
