Using your Injen AMSOIL Ea Nanofiber Dry Air Filter is easy. Just install it in your engine's air intake system following your vehicle's manual. During use, you'll notice better engine performance. When it comes to maintenance, every now and then, give it a light blast of compressed air to clean off dirt and debris. Since it's a dry filter, there's no need to oil it. This also helps prevent any issues with your MAF sensor. Keep an eye on its condition, and if you notice a significant drop in performance, it might be time for a more thorough inspection. But with proper care, this filter will serve you well for a long time.
