Using this intake system is easy. First, remove the old corrugated factory inlet hose from your 2021+ Acura TLX Type - S 3.0T. Then, install the 4 - ply silicone intake hose kit that comes with the product. Next, place the drop - in oiled panel air filter in the appropriate position. No need to calibrate the ECU, so you can quickly get back on the road. As for maintenance, regularly check the air filter. If it gets dirty, you can clean it following the manufacturer's instructions. Make sure to inspect the silicone hose for any signs of wear or damage over time. If you notice any issues, replace the parts as needed to keep your intake system working at its best.
