How to replace the air filter in a Subaru Impreza?

The air filter is located inside a housing in the engine compartment. Separate the cover halves and remove the air filter element. Remove the bolt holding the rear half of the air filter case, then release the spring clips to access the filter element for 2004 and earlier non-turbocharged models. For all other models, loosen the intake hose clamp, then unlatch the clips to access the air filter element. Inspect the outer surface of the filter element. If it is dirty, replace it. If it is only moderately dusty, it can be reused by blowing it clean from the back to the front surface with compressed air. Because it is a pleated paper type filter, it cannot be washed or oiled. If it cannot be cleaned satisfactorily with compressed air, discard and replace it. While the cover is off, be careful not to drop anything down into the housing. Wipe out the inside of the air filter housing. Place the new filter into the housing, making sure it seats properly. The remainder of the installation is the reverse of removal.

Subaru Impreza Air Filter

The purpose of a Subaru Impreza Air Filter is to filter air being drawn into the engine to prevent internal damage by dirt. When a vehicle moves, it sucks in air with dust, sand, leaves, and other particulate residues. The Air Filter traps contaminant particles as tiny as 5 microns so they do not enter the combustion chambers. A typical engine pulls approximately 10,000 gallons of air for every gallon of gasoline. Free flow through the Air Filter is critical for steady performance and optimum fuel economy. As time passes, the materials that have become trapped on the surface of the Subaru filter accumulate and may restrict airflow. Hence, the scheduled replacement of these filters is essential for the continued efficiency of the system. The design employs a fibrous, pleated medium that is housed within the intake system and seals tight so that all the air passes through the filtering element. The Impreza feels sluggish if the Air Filter becomes clogged as airflow reduces. By placing a clean Air Filter in a Subaru Impreza, full airflow can be restored while also ensuring that harmful contaminants are filtered away from the Impreza engine. Overall, this cheap and easy preventative will help enhance Subaru longevity.
