These CrossWind intake manifolds from Professional Products feature identical plenum and runner designs to the Typhoon. The main difference is that there is an open area under the plenum chamber. This feature is sometimes called an air gap design. The air flowing under the plenum provides a cooler charge for the incoming air with less heat transfer from the engine. This cooler air charge provides additional power.
