Using your Injen cold air intake is easy. First, make sure your engine is off and cool. Locate the existing air intake system and carefully remove it following the standard automotive removal steps. Then, install the Injen intake in its place, making sure all connections are secure. Once installed, start your engine and listen for any unusual noises. If everything sounds normal, you're good to go. When it comes to maintenance, check the Injen SuperNano - Web dry air filter regularly. If it looks dirty, you can clean it according to the instructions provided with the filter. It's important to keep the intake tube free from debris and any blockages. Also, make sure the heat shield and cover are properly attached at all times. Avoid driving through deep water or areas with excessive dust without taking extra precautions. If you have any concerns or questions during use, don't hesitate to contact Injen's customer service.
