Using this intake system is easy. First, remove the old factory inlet hose and air filter. Then, install the new 4 - ply silicone intake hose and the drop - in oiled panel air filter in their respective places. It's important to note that no ECU calibration is needed, so you can start using it right after installation. For maintenance, regularly check the air filter. If it gets dirty, you can clean it according to the instructions on the filter. This will help keep the intake system working at its best and ensure your vehicle gets the most out of it.
