Using the Injen air intake system is a breeze. First, make sure your vehicle is turned off and cool. Locate the old air intake and carefully remove it. Then, install the new Injen system, following the simple instructions that come with it. The Twist - Lock System makes the installation quick and easy. As for maintenance, regularly check the SuperNano - Web dry air filter. If it looks dirty, gently clean it with a suitable filter cleaner. Avoid using harsh chemicals that could damage the filter. Also, keep an eye on the connections to ensure they're tight and secure. This will help your Injen air intake system perform at its best for a long time.
