You can Select Your Vehicle to check if 17801-22020 fits your vehicle.

The air filter is located inside a housing at the left (driver's) side of the engine compartment. To remove the air filter, release the spring clips that keep the two halves of the air cleaner housing together, then lift the cover up and remove 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. Caution: Never drive the vehicle with the air cleaner removed. Excessive engine wear could result and back-firing could even cause a fire under the hood. 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 cover is the reverse of removal.
