Using this DC Sports Short Ram Intake is easy. First, gather all the hardware that comes with the kit. Remove the old, restrictive OEM rubber intake pipe from your 2003 - 2006 Nissan 350Z or Infiniti G35. Then, install the smooth mandrel - bent aluminum tubing in its place. Attach the high - flow DC Sports performance air filter to the tubing. No cutting or modification is needed, so you can complete the installation without any extra tools or skills. As for maintenance, check the air filter regularly. If it looks dirty, clean it according to the instructions on the filter. This will help keep the intake system working at its best. Also, make sure all the connections are tight to prevent any air leaks. When driving, your vehicle should have improved performance and throttle response, thanks to this intake system. And don't worry about emissions, as it meets the standards in all 50 states of the USA.
