Pulled this off of my 11 Sonata 2.4 GDI over the weekend, has 4200 miles on Castrol Edge 5w40. Replaced it with Edge 0w40 and a Hastings LF565. Filter seems solidly built, media isn't brittle and has no tears. Got it fron my local NAPA as I wanted to dissect it after use. Worst thing about them is that there is nada for information on these filters out there, and their website, provided you can find it, is useless, so unsure of micron rating. Even asked our shop's NAPA rep, and he couldn't find anything either.
