Using this DC Sports Short Ram Intake is easy. First, gather all the parts included in the kit. Then, remove the old restrictive OEM rubber intake pipe. Next, install the smooth mandrel - bent aluminum tubing in its place. Attach the high - flow air filter. Make sure all the connections are tight. You don't need to make any cuts or modifications during the installation. As for maintenance, check the air filter regularly. If it's dirty, clean or replace it. This will keep your intake system working well. And remember, since it's C.A.R.B compliant, it'll meet emissions standards no matter where you are in the USA.
