Using the Injen RD Series Cold Air Intake is easy. First, make sure your engine is cool before installation. Remove the old air intake system carefully following the instructions in the kit. Install the new intake tube and connect it properly to the engine. Attach the Injen SuperNano - Web dry air filter. After installation, start your engine and check for any loose connections. When it comes to maintenance, regularly inspect the air filter. If it's dirty, clean it according to the filter's cleaning instructions. You can use a special filter cleaner. Make sure to dry it completely before reinstalling. Keep an eye on the intake tube for any signs of damage or leaks. If you notice any issues, contact Injen's customer service. Remember, this intake is designed for specific models, so don't try to use it on other vehicles without proper modification.
