Using this intake system is easy. First, make sure your car is turned off and cool. Remove the old factory inlet hose and replace it with the 4 - ply silicone intake hose that comes in the kit. Then, install 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 the improved performance. As for maintenance, check the air filter regularly. If it looks dirty, you can clean it following the instructions on the filter. Also, inspect the silicone hose for any signs of wear or damage. If you notice any issues, replace the parts as needed. And don't forget to visit the blog link for more tips and updates.
