The oil filter on your Subaru Impreza is one of the most important parts in the lubrication system. The filter is designed to remove particles of varying sizes from the engine oil, allowing the oil to better do its job. If your oil has dirt or metal particles in it, the piston walls and bearings can be damaged. It is important to change the oil and filter regularly to maintain a well-lubricated engine and protect all of the internal components.

Things you need
- Car ramps
- Wheel chocks
- Oil drain pan
- Socket set w/ extension
- Oil filter wrench
Position a set of car ramps in front of the front tires of your Impreza. Carefully drive the cars up on the ramps and place a chock behind the rear wheels of the car.
Place an oil drain pan under the oil pan drain plug. Remove the drain plug with a socket and ratchet, allowing the oil to drain into the pan.
Locate the oil filter on the engine block. It is on the passenger side about halfway back on the bottom of the engine. It is tucked up behind the oil pan and exhaust, so you will have to look up from under the engine to see it.
Slide the oil drain pan under the filter and remove the filter from the engine with an oil filter wrench. There are several styles of filter wrench available but because of the location of the filter, the stamped steel ones that slide on the base of the filter and are turned with a ratchet are the best for this car.
Make sure the rubber gasket comes off with the filter. Place the oil filter in the oil drain pan and allow the old oil to drain out of it before disposal.
Tips and warnings
- The oil could be hot, so use caution when draining it out of the oil pan.
