Using this intake system is easy. First, make sure your car is a 2018+ Honda Accord 1.5T. When installing, use the factory rubber grommet as instructed. Attach the bracket properly so the silicone tube doesn't touch the front factory bracket. There's no need to calibrate the ECU, which saves you time and hassle. For maintenance, regularly check the high - flow drop - in oiled panel air filter. If it gets dirty, clean or replace it according to the filter's instructions. Keep an eye on the 4 - ply silicone intake hose for any signs of wear or damage. With proper use and care, this intake system will keep your car running smoothly and improve its performance.
