Got my intake last week and installed it today. I believe the mounting differs from one Fit to another. Mind is an AT and the mounting point is right under the air filter where I saw a pic from another thread and its mounting point is near the trans. For mind, the bracket does cut into the radiator host, had to do some mod to band the bracket and using the flat connector to make it work. Took about an hour for the whole thing, not too bad.
Haven't test drive yet. Will do it now.

Made a short trip around the area, quite loud at higher RPM. Acceleration seemed smoother, feels like lots of power because of the sound
Will monitor fuel consumption. All in all I think it's a good deal.
