2. Carefully set the cover aside and remove the existing air filter from the inside of the air box 

3. Clean any debris that may be inside the top cover and on the walls of the air box (a dry cloth works best; do not use any liquids as your air box should always remain dry

4. Drop-in the new K&N Air Filter, ensuring the fin on the filter is being placed in the correct position 

5. Replace the air box top cover, by aligning the two hooks on the side of the box, back in place (opposite side from the security clips)
