Using your Injen cold air intake is easy. First, make sure your engine is off and cool. Locate the stock air intake system in your vehicle and carefully remove it. Then, install the Injen intake following the included instructions. It usually involves connecting the intake tube to the engine and securing the air box. When using the intake, remember not to rev the engine too hard right after starting, especially in cold weather. This gives the engine time to adjust to the increased airflow. For maintenance, check the Injen SuperNano - Web dry air filter regularly. If it looks dirty, you can clean it according to the cleaning instructions provided. It's a good idea to clean the filter every few months, depending on your driving conditions. Also, periodically inspect the intake tube and air box for any signs of damage or loose connections. If you notice any issues, contact Injen's customer service for assistance.
