Using this intake system is easy. First, make sure your vehicle is turned off and cool. Then, remove the factory corrugated inlet hose and the old air filter. Install the new 4 - ply silicone intake hose in place of the factory one, and insert the drop - in oiled panel air filter. There's no need to calibrate the ECU, so you can start your vehicle right away and enjoy the improved performance. As for maintenance, check the air filter regularly. If it looks dirty, you can clean it according to the manufacturer's instructions. Also, inspect the silicone hose for any signs of wear or damage, like cracks or leaks. If you notice any issues, replace the parts as needed to keep your intake system working at its best.
