Iím not my clear what you are asking? I simply added it for cooling purposes. While monitoring IATS, it CLEARLY brought temperature down dramatically. So it did exactly what installed it for. Did I NEED it?? No. But it is a pretty simple setup
In my M4, I am using it as a fuel source given I can only get crappy 91 octane here in CA. Of course the E40 mix helps too. But the S55 is a much diifferent platform and does not suffer from heat soak issues
