Once the flap is closed, it is quite tight and is hard to manually push open. I observed all these with filters removed. The loud wind blow with AC MAX sometimes covers the noise, but most of the time it's fairly noticeable, like a whack on the dash 2 seconds after wind starts to blow.
Now I'm paranoid. It seems everything I replaced on this car so far gives me some sort of problems.
Just to be sure. How would the bottom filter sit exactly? Front end below the front tap and rear end below the three little protruding plastic arms?

Truthfully I only remember the front tab highlighted in yellow. I would have to remove it again to take a look.
