Using your K&N Universal Air Filter is easy. First, find the right spot in your equipment's air intake system where the filter will fit. Make sure the filter is correctly aligned and attach it securely using the rubber flanges. When it comes to maintenance, regularly check the filter for dirt and debris. Once it gets dirty, you can wash it. Just use a mild soap and water, then let it dry completely before reinstalling. As for storage, keep it in a dry place away from direct sunlight. Also, make sure to double - check the fit for your specific vehicle model, especially if you're using the stretch feature of the rubber flanges.
