Using the Injen RD Series Cold Air Intake is easy. First, make sure your vehicle is turned off and cool. Locate the original air intake system and carefully remove it. Then, install the new Injen intake following the included instructions. It's important to double - check all connections to ensure they are tight. When it comes to maintenance, regularly inspect the Injen SuperNano - Web dry air filter. If it looks dirty, it can be cleaned according to the filter's cleaning guidelines. This will keep the airflow at its best and maintain the performance of the intake. As for general use, don't expose the intake to excessive water or other contaminants. If you drive in dirty or dusty conditions, check the filter more often. With proper use and maintenance, your Injen intake will serve you well for a long time.
