Where is the oil filter on a 2007 saturn ion located.?

The Ion uses a metal-free cartridge filter. You will see the oil filter housing under the hood. It is black and round, with a nut on the cover, and is cast into the engine block. You'll need a low-profile 6-point oil filter canister socket (don't know the size) to remove the cover to access the filter. You can find it at PepBoys for less than $10 by the other oil change supplies.Where is the oil filter on a 2007 saturn ion located.?
if it's the 4cylinder engine, it' on top of the engine next to the head. it has a black cap. i think it's a 27mm socket to remove.
