Using your Injen Nanofiber Sur - Loc Dry Air Filter is easy. Just install it in the appropriate place in your engine's air intake system as per your vehicle's manual. When it comes to cleaning, a light blast of compressed air will do the trick. This will remove most of the dirt and debris. As for maintenance, check the filter regularly, especially if you drive in dusty or dirty environments. There's no need to oil the filter, so avoid using any oil products on it as this can damage the MAF sensor. Keep it clean and it will keep your engine running smoothly for a long time.
