Using your Injen AMSOIL Ea Nanofiber Dry Air Filter is straightforward. Just install it in your vehicle's air intake system following the manufacturer's instructions. When it comes to maintenance, a light blast of compressed air is all you need to clean it. This will remove most of the dirt and debris. You don't need to oil the filter, so there's no risk of over - oiling and dirtying your MAF sensor. Make sure to clean the filter regularly, especially if you drive in dusty or dirty conditions. Check the filter every few months to see if it needs cleaning. If it looks very dirty or clogged, clean it right away. Store the filter in a dry place when not in use to keep it in good condition.
