Behold! The fabled "custom" Wix filter made exclusively for the Mazda Skyactiv platform. As you can see from the C&P, not much custom about it. This filter was in use for a little over 7k miles and two days shy of eight months. Held up great and would definitely use again, in fact, it was replaced with another 57002. However, I wouldn't bend over backwards to use ONLY this or OE filters like some Mazda fans claim. To compare with other filter options you can compare to the following; Denso 150-2002, Fram XG6607, Mazda PE01 14 302A, and Purolator PL14612.
