Using your K&N XStream Universal Air Filter is easy. First, find the right spot in your vehicle's air intake system for the filter. The rubber flange can be stretched a bit if needed to fit properly. Once it's in place, make sure it's securely attached. When racing or driving, this filter will give you great air flow and protection. For maintenance, you can wash the filter when it gets dirty. Just use a mild cleaner and water, then let it dry completely before reinstalling. Keep in mind that it's important to check the filter regularly to ensure it's in good condition. If it's damaged, it's time to replace it.
