Using your Injen NanoWeb Dry Air Filter is easy. Simply install it in your vehicle as per the manufacturer's instructions. When it comes to maintenance, give it a light blast of compressed air to clean it. There's no need to use oil on the filter, which helps keep your MAF sensor clean. Always make sure to check the filter regularly, especially if you drive in dusty or dirty conditions. If you notice a significant drop in performance, it might be time for a more thorough cleaning. Store the filter in a dry place when not in use to maintain its effectiveness.
