This is similar to the intake manifold "turtles" that became popular on the Mopar Magnum engines. Basically, a small pyramid bolted to the flat bottom of the intake manifold to help direct air towards the runners. Multiple designs are offered based on RPM range.
These have been independantly proven to add a couple hp.
