Using your K&N replacement air filter is easy. First, locate the air filter housing on your Arctic Cat vehicle. Open it up carefully and remove the old filter. Then, place the new K&N filter in the housing, making sure it fits snugly. Close the housing securely. When riding in dirty and dusty areas, check the filter more often. If it looks dirty, it's time to clean it. To clean the filter, use a K&N filter cleaning kit. First, spray the cleaner on the filter and let it soak for a few minutes. Then, rinse it gently with water. Make sure it's completely dry before applying the K&N filter oil. Apply the oil evenly across the filter. Let it dry again before reinstalling it. Always follow the maintenance schedule in your vehicle's manual and keep an eye on the filter's condition for optimal performance.
