Using this DC Sports Short Ram Intake is easy. First, gather all the hardware that comes with the kit. Then, remove the restrictive OEM rubber intake pipe from your 2008 - 2016 Mitsubishi Lancer 2.4L A/T. Next, install the smooth mandrel - bent aluminum tubing and attach the high - flow air filter. Make sure all connections are secure. When it comes to maintenance, check the air filter regularly. If it looks dirty, clean or replace it as needed. Keep an eye on the intake system for any signs of damage or loose parts. Since this intake system meets emissions standards, you don't have to worry about any legal issues when using it in the USA. Just enjoy the improved performance and throttle response of your vehicle.
