It looks good and fits perfectly; other than that, I have no idea how to tell if it's better or worse than anything else.

Great OEM replacement at hlaf the cost
Looks exactly like the OEM filter a quality product. it is the same size fit and performance. Filter replacement is fast 10 min tops, it's crazy how much a dealer charges to replace it.
