Easy to Own
-
While the big port volume is there, it is large where it needs to be and left alone where it needs to be left alone. The port entry is sized properly in relation to the throat and valve size. This shape allows you to easily adapt your existing intake manifold without major modification. This also allows you to go back and forth between manifolds for testing without having to port match and hog manifolds out to some big square port.
