Air filter question (2 Viewers)

[FarmerFox]

That pillow is wild and, since it has white fiber inside, looks to be a simple large particulate filter. The engine air cleaner IPL shows 1770170180 connects directly to the air intake pipes before the replaceable air filter. This "pillow" will need cleaning, collect debris under it, and/or need replacement. Why didn't Toyota use simple push pins that allow the pillow to be popped out and debris vacuumed out?
