Professional Products Crosswind Satin Manifold for Small Block Mopar features a satin finish. This CrossWind manifold is designed so that the same model fits both the 318-340-360 engine series and the late Magnum V8s. The manifold features an air space under the plenum chamber which allows air to pass through keeping the incoming fuel/air charge cooler than is possible with a conventional design manifold. The power plus CrossWind for Mopar also features nitrous bosses, an extra water port at the rear of the manifold and is available in a satin finish or highly polished show finish. The manifold is designed to accept the standard length bolts that come on factory engines. It has special finishing plugs which are provided to attractively cap off the unused bolt holes.
