Using your DC Sports Short Ram Intake is easy. First, make sure your engine is cool. Then, install the intake following the included instructions. When driving, you'll notice improved engine performance right away. As for maintenance, check the air filter regularly. Since it's oil - free, you just need to clean it with a mild cleaner and let it dry completely. Keep the intake away from water puddles to avoid damage. If you're not sure about any part of the installation or maintenance, consult the user manual or contact DC Sports customer support.
