Using the Injen Evolution Air Intake is straightforward. First, make sure your vehicle is turned off and cooled down. Locate the original air intake system and carefully remove it following the instructions provided in the installation guide. Then, install the new Injen intake using the Twist - Lock System. It's designed to be easy, so don't worry about complex steps. When it comes to maintenance, check the SuperNano - Web Dry Air Filter regularly. If it looks dirty, you can clean it according to the cleaning instructions. Also, keep an eye on the hardware like the band clamps and silicone coupler. Make sure they are tight and in good condition. If you notice any loose parts or signs of wear, replace them promptly. And always refer to the product manual for more detailed information and specific instructions.
