Using your Injen intake is easy. First, install the intake following the included instructions. It doesn't need any aftermarket tuning, so you can start using it right after installation. When you want to switch to a cold air kit with ram air or a snorkel, simply attach the separately - sold EVO15069 Ram Air Scoop or the EVO15070 Snorkel. As for maintenance, check the intake regularly for any signs of dirt or damage. Clean it with a mild cleaner when it gets dirty. Make sure the stainless - steel hardware stays tight and the urethane couplers are in good condition. Keep in mind that the scoop and snorkel are sold separately, so if you want to use them, you'll need to purchase them separately. And always follow the safety instructions during installation and use.
