Using your Injen SuperNano Web Dry Air Filter is easy. Just install it in your vehicle's air intake system according to the instructions provided. When it comes to maintenance, a light blast of compressed air can clean it up. You don't need to use any oil on this filter, which helps prevent issues with your MAF sensor. Make sure to check the filter regularly, especially if you drive in dusty or dirty environments. If you notice a significant drop in performance or the filter looks really dirty, it's time to clean it. Store the filter in a dry place when not in use to keep it in good condition.
