Just a note....everything is stamped "UP" on the plastic and stock filter. You will note that the air flow is DOWN based on the crud on the top of the filter. Remember that when you install the filter based on the air flow....it flows down from the outside into the hvac blower housing. The filter I bought had the arrow for airflow, which is down.
