Using the DC Sports Short Ram Intake is simple. First, gather all the hardware that comes with the kit. You don't need to make any cuts or modifications to install it. Just replace the old, restrictive OEM rubber intake pipe with the smooth mandrel - bent aluminum tubing included in the kit. Attach the high - flow air filter. When you're done, your car should have better performance and throttle response. As for maintenance, check the air filter regularly. If it looks dirty, you can clean it according to the instructions on the filter. This will help keep the intake system working well. And remember, since it's C.A.R.B compliant, you won't have any issues with emissions tests in the USA.
