Where is the air filter located in the engine compartment on Subaru Legacy?

The air filter is located inside a housing in the engine compartment. To access it, separate the cover halves and remove the air filter element. This involves removing the bolt holding the rear half of the air filter case, then releasing the spring clips. Loosen the intake hose clamp, then unlatch the clips to get to 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. However, 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. Never drive the vehicle with the air cleaner removed, as excessive engine wear could result. Wipe out the inside of the air cleaner housing. Place the new filter into the air cleaner housing, making sure it seats properly. Installation of the housing is the reverse of removal.
