Using your K&N XD air filter is straightforward. Just clamp it on to the appropriate spot in your vehicle as per the fitting instructions. When it comes to maintenance, clean it regularly to keep it performing at its best. You can clean it in the same way as K&N's original cotton air filters. Make sure to check it often, especially after off-road adventures in dusty conditions. If it looks dirty or clogged, it's time for a cleaning. When cleaning, use a gentle cleaner and follow the cleaning steps carefully. Avoid using harsh chemicals as they might damage the filter. Store the filter in a dry place when not in use to prevent any moisture damage.
