FIAV stands for fast idle air valve.

o ok, well this is a block off plate for that? what is the purpose or benefit of doing that?

Well if your not having any idle problems you shouldnt do it.
It helps warm your car up faster on cold starts.
The fiav has wax inside of it when you first start the car the wax is hard so it lets more air through, this is why you idle higher on start up(so it warms up faster)Then when the coolant temps raise the wax melts and doesnt let air through.

rather than getting a plate i blocked mine with some quick steel works great. No more REV bounces at 4:30 when i am off to work
