Using your Injen Super - flow Web Nanofiber Dry Air Filter is easy. Just install it in the designated air intake area of your vehicle as per the manufacturer's instructions. When it comes to maintenance, every now and then, give it a light blast of compressed air to remove dirt and debris. Since it's a dry filter, you don't need to oil it. Avoid using any harsh chemicals or excessive force when cleaning. If you notice a significant drop in performance or if the filter looks overly dirty, it might be time to clean it. Keep in mind that proper installation and regular maintenance will ensure your filter works well and protects your engine for a long time.
