Replacing the air filter box mounting bolts - Toyota Celica, 2.0L, 1998

Replacing the air filter box mounting bolts.
It's simple: I
unscrewed one bolt from the front strut, loosened the opposite bolt, bent the strut, disconnected the air duct, removed the cover, unscrewed 3 bolts, pulled out the box.

At the bottom turned out to be sooo much dirt, which got there from under the non-original bolts and from under the wheel arch liner.

I fixed the box with three original bolts: everything fell like a factory.
I changed the air filter and assembled it in the reverse order.
