Air Filter Efficiency?
When I compared the filters, the OEM one had about 40 folds, but the one from ebay had 34 folds. Less folds, but the paper was a little thicker and more fluffy.
I'm wondering how the different designs affect the efficiency of the filter and being able to push air out into the cabin. It is supposed to be with more folds we have larger surface area, but there is a difference in the thickness/fluffiness of the paper too. not really sure how it works out to which one is better. (not that it matters much since it is just the cabin air filter)
