Using this Injen intake is easy. First, make sure your vehicle is turned off and cooled down. Then, follow the included instructions to remove the old intake system. Install the new intake, using the patented Twist - Lock mounting system on the air filter for a secure fit. For best results, keep the filter clean. If you have the oiled filter, check it regularly and re - oil it as needed. When cleaning, use a mild cleaner and let it dry completely before re - installing. If you choose the dry filter, a simple vacuum or gentle blow - off can keep it in good shape. Always refer to the vehicle's manual and the intake's instructions for specific details. And remember, if you have any questions, you can reach out to our customer service team.
