Using this DC Sports cold air intake is easy. First, gather all the hardware that comes with the kit. You don't need to cut or modify anything, just follow the included instructions to install the smooth mandrel - bent aluminum tubing and the high - flow air filter in place of the old OEM rubber intake pipe. When using your car, the intake will work continuously to improve performance. As for maintenance, check the air filter regularly. If it looks dirty, you can clean it according to the manufacturer's instructions. Keep an eye on the tubing for any signs of damage, like cracks or dents. If you notice any issues, contact DC Sports customer service for assistance.
