Using this PLM heat exchanger is quite straightforward. First, gather basic hand - tools as it's a direct bolt - on installation near the stock location. But remember, we recommend getting a professional to do the installation as instructions aren't included. When your turbocharged Infiniti Q50 or Q60 3.0TT (2016 - 2020 models) is running, the heat exchanger will work to cool down the intake charge temperature, which helps maintain power. This is especially useful in hot weather or during extreme driving. As for maintenance, regularly check the corrosion - resistant coating. If you notice any signs of damage, it might be a good idea to have it inspected. Also, make sure that the heat exchanger is expelling all air as it's designed to do. If you experience any overheating issues, the heat exchanger could be a culprit, so have it checked. Overall, this heat exchanger is built to last with its all - aluminum construction and high - density fin core, but proper care will ensure its long - term performance.
