Using this Perrin front mount intercooler piping kit is straightforward. First, carefully follow the installation instructions provided. Make sure all connections are tight and secure, especially the hose clamps on the oversized beaded ends of the boost tubes. When using your Subaru WRX, the kit will help improve air flow and engine performance. As for maintenance, check the clamps periodically to ensure they haven't loosened. Keep an eye on the coolant reservoir aluminum catch can and empty it if it gets full. There's no need for special tuning, but if you notice any unusual noises or a drop in performance, have the kit inspected. Remember, it's designed to work with the PERRIN Front Mount Intercooler (sold separately), so make sure that component is in good condition too. With proper use and maintenance, this kit should serve you well for years, thanks to its 5 - year manufacturer warranty.
