Using your Injen RD Series Cold Air Intake is easy. First, make sure your engine is cool before installation. Follow the included instructions carefully to attach the intake to your vehicle. Once installed, start your engine and enjoy the increased power and unique sound. As for maintenance, check the Injen SuperNano - Web dry air filter regularly. When it gets dirty, you can clean it according to the filter's cleaning instructions. It's also a good idea to inspect the intake tube for any signs of damage or debris. Remember, this intake is designed for specific vehicle models (2004 - 2006 Pontiac Vibe GT and 2005 - 2006 Toyota Corolla XRS), so don't try to use it on other vehicles unless it's compatible. And always keep in mind that regular maintenance will help your intake perform at its best for a long time.
