Hi! I hope someone can help me, I changed my own cabin air filter in my 2012 crv, I placed the filter with the arrow pointed down. But is there like a front or back to the filter when placing it back in or does it not matter as long as the arrow is down? It's an stp filter if that matters. Thanks for any help!!! Ps- my ac is really weak so I am hoping this helps.
