Depends on the oil filter you are looking for ;) They vary quite a bit. And well, you didn't include a year, or model.
If you are into FRAM (available most anywhere, including most Walmarts), here's what I came up for the 2008 Kia Optima:
EXTRAGUARD PH9688
TOUGHGUARD TG9688
V6 L14459 or PH9688
For the 2001 kia optima I have found the oil filter between the front passenger side tire and the engine. You can see it if you turn the wheels all the way to the left, although it helps if the filter cover is a bright color. To change it I had to remove the tire.
type and number to use for kia forte
The auto parts store tonight sold me 4 quarts for the oil change... Optima 2001 4 banger... The actual amount of oil needed for an 1999 - 2003 Optima 4 cyl. is 4.5 qts. and 4.75 qts. for the V6. They use the same size oil filter.
or mopil xhp that's very good the 2003 kia optima uses 5w-30
WE recommend 5W30
At the bottom of the engine block.
5-20

The oil filter on the Kia Sportage is found on the driver's side of the engine. The oil filter should be replaced during an oil change.
Kia makes automobile but they do not manufacture oil filters. Their filters are made by a filter manufacture and then Kia is printed on the side. Use any quality filter in your Kia. Purolator, Bosch, Wix, are all quality filters you can use.
