Wilson Manifolds - the leader in induction design and technology - has joined forces with Pro-Filer Performance to produce the latest SBC 23° Intake Manifold. The Pro-Filer / Wilson intake manifold has shown a 25 HP gain over the competition in independent dyno testing. The Pro-Filer / Wilson intake features a 4150 carb flange and fuel injection bosses cast on the manifold.
This is not a shelf piece, the manifold must be ported to the customers specifications after it has been purchased.
