A different (but related) tidbit that CX-5 owner's who plan to buy 3rd party filters should be aware of is this:
Mazda specifies a different filter for the Skyactiv engines vs. some earlier, non-Skyactiv engines. Both filters have the same dimensions and will physically mate to either engine but the filter for Skyactiv engines has a significantly different bypass pressure. But here's the problem: Some 3rd party filter manufacturer cross reference the same filter to either engine.
So beware if buying non Mazda filters (which I don't know why anyone would want to with the low price and high quality of the OEM filters).
