Using this Perrin intercooler piping kit is a great way to upgrade your Subaru WRX. First, make sure you have all the tools required for installation as mentioned in the included instructions. When installing, take your time to ensure all connections are tight, especially the hose clamps on the beaded ends of the boost tubes. During use, keep an eye on the coolant reservoir catch can and empty it when it gets full. For maintenance, regularly check the condition of the powder - coated finish. If there are any signs of chipping or rust, you can touch up the affected areas. Also, inspect the hose clamps and couplers for any signs of wear or loosening and tighten or replace them as needed. Remember, this kit is designed to work with the PERRIN Front Mount Intercooler, so make sure it's installed correctly for the best performance.
