Using the Mishimoto Performance Intercooler Pipe Kit is straightforward. First, make sure your engine is cool before starting the installation. Carefully remove the stock pipes from your 2016 - 2021 Honda Civic 1.5T or 2017 - 2020 Civic Si. Then, install the new pipes from the kit in the same place. Connect all the couplers tightly to avoid air leaks. When it comes to maintenance, check the pipes and couplers regularly for any signs of wear or damage. You can clean the pipes with a mild soap and water solution to keep them in good condition. If you notice any cracks or loose connections, replace the parts right away. Also, be careful when working around the engine to avoid any burns or injuries. With proper use and maintenance, this intercooler pipe kit will serve you well for a long time.
