Just got a replacement cabin air filter (ACDelco equivalent of GM part number 15861929). There is an arrow on it with the word "Flow" next to it. Do I insert the filter with the arrow pointing up or down? Seems like the flow goes down?

Install it just like the old one that you will remove.

You are correct. Air flow from outside to inside. Arrow points down.

Actually, this answer can be incorrect. I have seen some that came in the car saying "this side up" with an arrow pointing up. Many of the replacements say "flow" with an arrow pointing the way the air should flow. So when these are in place, the arrow should be pointing down instead of up like the original filter.

Thanks for the responses. I was hesitant because the one I had originally (part number 15848592) had the "this side up" with the arrow pointing up. For those wanting to replace their cabin air filter, don't get the 15848592 part. Get the 15861929. It's a much sturdier design.

I just changed my cabin filter. Not that this is a critical part of the car, but from the factory it was installed with the ARROW POINTING UP. So, unlike the previous few posters, I don't think the arrow indicates flow, rather the orientation of the filter.

As I remember... the bottom goes down, the top goes up

Arrows? Arrows? We don' need no steekin' arrows?

It should look like the one you take out and go in the same way.
