Using your K&N Universal Air Filter is easy. Just find the right spot for it based on your equipment's air intake, and attach it securely to the intake. Make sure the rubber flange fits tightly to prevent air leaks. When it comes to maintenance, keep an eye on the filter's dirt level. Once it looks dirty, it's time to clean it. To clean, gently wash the filter with a mild detergent and warm water. Rinse thoroughly and let it dry completely before reinstalling. Avoid using harsh chemicals or high - pressure water as they can damage the filter. Also, always check the rubber flange for any signs of wear or damage after cleaning and during use. If you notice any issues, it might be time to replace the filter to ensure optimal performance.
