Using this Mishimoto intercooler pipe kit is easy. First, make sure your vehicle is turned off and cooled down. Carefully remove the old factory intercooler pipe. Then, install the new polished aluminum piping from the kit. Connect the silicone couplers using the provided T - bolt clamps. Make sure all connections are tight. As for maintenance, regularly check the clamps to ensure they're still tight, especially after long drives or high - performance use. If you notice any signs of wear on the silicone couplers or piping, replace them promptly. Also, keep the kit clean to prevent debris from building up. And remember, this kit comes with a lifetime warranty, so if you have any issues, don't hesitate to contact Mishimoto.
