Grasp the front section of the engine cover and lift it straight up. Pry up on each of the sides of the engine cover at the point where the front and rear sections meet.

Push back on the metal clip at the center of the rear of the engine cover. Pull the cover off and set it aside.

Insert the new air filter into the air cleaner assembly. Replace the lower portion of the assembly and tighten the Torx screws with the Torx bit and ratchet. Install the air cleaner assembly onto the mounting area in the engine compartment.

Put the new filter in the old one's place.

Replace the cover on the air filter compartment and lock it down, either by snapping the clips shut or replacing the screws.
