Using your Injen NanoWeb Dry Air Filter is easy. Just install it in place of your old air filter according to your vehicle's manual. When it comes to maintenance, give it a light blast of compressed air every once in a while to keep it clean. Since it doesn't need oil, you can avoid the hassle of oiling and the risk of dirtying your MAF sensor. As for precautions, make sure to handle it gently to avoid damaging the pleats. Also, always check for any signs of wear or damage. If you notice anything unusual, it might be time to replace the filter. This way, you can keep your engine running smoothly and enjoy the performance benefits for a long time.
