Kia says their OEM filter will last the 7500 miles or 6 months,whichever comes first. Personally,I would never push a filter beyond this point. The K&N HP-1004, the Mobil1 M1-104,and the Purolator Pure One PL14459 should all work just fine in the range mentioned above. However........if you off-road a lot and **** up a lot of dust where you live............I would change the filter every 3 months or 3000 miles. The Amsoil filter you said was leaking........was it loose or what? I am curious about that. Was it a SDF-20?
ps: if you changed your own oil the first time....you probobly remember thinking that an 800 pond gorilla put the original Hyundai/Kia filter on! It was a bear to break loose and it left the gasket stuck to the engine flange on mine. Maybe that's why Kia screwed it on so tight....to stop leaks.
