It's at the bottom, right next to the oil pan. It's a paper cartridge type filter, under a plastic cover. You need to have a special tool to remove the cover. When you install the new filter it has to pop inside the cover, it needs to be forced a bit, but you will notice it. Just remove the cover together with the filter, remove the drain plug from the oil pan, let the oil drain from both location. Lube and replace the filter and the O-ring on the filter cover. Reinstall both and tight them to the specific torque. Fill oil to the crank case. Reset service reminder.
