Mine is actually a 3 port and the benefit is purely convenience.It has one rear output and 2 front outputs. Having that saves a Tee at the frame for the two front lines.
It actually came with a plug for the second front output. The two of them are connected internally.
I went with the
Wilwood because it was on sale for less than the
Speedway branded one when I was ordering.
Edit: Apparently they call mine a 4 port (which seems odd since it has 2 inputs and 3 outputs) and the Speedway one a 3 port (having 2 inputs and 2 outputs).
Maybe I don't know what "port" means in this context?
