Using this intake system is straightforward. First, make sure your car is turned off and cooled down. Then, remove the factory corrugated inlet hose and replace it with the 4-ply silicone intake hose from the kit. Next, install the high-flow drop - in oiled panel air filter. That's it! You don't need to do any ECU calibration. As for maintenance, check the air filter regularly. If it gets dirty, clean it according to the manufacturer's instructions. Also, keep an eye on the silicone hose for any signs of wear or damage. If you notice any issues, replace the parts as soon as possible to keep your intake system working at its best.
