Using this air intake system is easy. First, make sure your engine is cool. Then, remove the old air intake following your vehicle's manual. Install the aFe Pro Dry S system in its place, ensuring all connections are secure. When using it, avoid driving through deep water as it can damage the intake. For maintenance, check the air filter regularly. If it's dirty, clean it according to the instructions. Also, keep an eye on the intake hoses for any signs of wear or damage and replace them if needed.
