Using your new 2019+ Acura RDX 2.0T Stage 1 Intake System is easy. First, find a safe and stable place to work on your car. Remove the old corrugated factory inlet hose carefully. Then, install the new 4 - ply silicone intake hose kit that comes with the package. Make sure it's properly connected. Next, insert the drop - in oiled panel air filter. There's no need to calibrate the ECU, so you can start your car right away and enjoy improved performance. As for maintenance, check the air filter regularly. If it looks dirty, clean it or replace it as needed. Keep the silicone hose free from debris and damage. If you notice any unusual noises or a drop in performance, have your intake system checked by a professional.
