Offenhauser Port-O-Sonic Intake Manifolds
Offenhauser Port-O-Sonic intake manifolds are designed for competition only. They feature special plenums and runners configured to match the volume of each specific engine, in order to produce maximum power. They eliminate the lean/rich conditions found from runner to runner in most aftermarket manifolds; and they're dyno-proven to increase power across the entire rpm range. Increases can start as low as 2,000 rpm and go as high as 8,500 rpm.
