Using your Injen Super Nano - Web Dry Air Filter is easy. Just install it in place of your old air filter following your vehicle's manual. When it comes to maintenance, if you notice a drop in performance or a dirty filter, you can clean it with a light blast of compressed air. There's no need to use oil, which simplifies the process and keeps your MAF sensor clean. Make sure to check the filter regularly, especially if you drive in dusty or dirty environments. When cleaning, be gentle with the compressed air to avoid damaging the filter. This will keep your engine running smoothly and ensure the filter performs at its best for a long time.
