I just purchased a new air filter for my 2001 Camry LE 4 cyl. When I opened the air filter box, I found a pile of yellow insulation that looked like a mouse had made a nest in the box. It was under the air filter.
I talked to one of my friends that has the same car and he said that when he looked in his air filter box, he had the same pile of yellow insulation.
Does anyone know what the purpose of this material in the air filter box is for? Should I remove it or should I leave it there?
Thanks.
