When you pull the cabin air filter out from the compartment, is the air supposed to go from bottom to top, or top to bottom? I ask because the new filter I get has a direction arrow for the air to go, but the old stock filter doesn't tell me where the airflow is supposed to go. Thanks Alex
If you look at the top of the original filter, you may note that it's filthy and full of dirt. This is a clue as to air flow direction. What kind of filter are you using to replace the original?
