I am just curious where my engine air filter is taking air from.
Below is a picture of my car's (Toyota Vitz 2007) engine (not a picture of my exact engine).
As I can see, the air filter should take air from the place I have circled in red. If I block air intake with my hand, engine doesn't even seem to notice it. If it was actually the place the engine takes air from, I would expect the engine to stall when I block it.
So isn't this the place where the air filter draws air from? If it is, why didn't engine stall when I block it?
