Using this Mishimoto intercooler pipe kit is straightforward. First, make sure your vehicle is turned off and cooled down. Then, carefully remove the old intercooler pipes. Install the new pipes in the same place as the old ones, connecting them tightly with the included couplers. Check all connections to ensure there are no loose parts. As for maintenance, it's a good idea to regularly inspect the pipes and couplers for any signs of wear or damage. If you notice any leaks or the couplers seem loose, tighten them up or replace them if necessary. Also, keep the pipes clean to maintain good airflow. When cleaning, use a mild detergent and a soft cloth. Remember, this kit is designed for specific Mitsubishi Lancer Evolution models, so don't try to use it on other vehicles unless you're sure it will fit.
