Using your K&N Universal Tapered Air Filter is easy. First, find the right spot in your equipment's air intake system. The pliable rubber flange can be stretched a bit if needed to fit properly. Make sure it's securely attached to avoid air leaks. When it comes to maintenance, check the filter regularly. If it looks dirty, it's time to clean it. You can wash the filter with a gentle cleaner and warm water. Rinse it thoroughly and let it dry completely before reinstalling. Avoid using harsh chemicals as they can damage the filter. With proper care, your K&N filter will serve you well for a long time.
