Its main purpose is to improve air distribution between cylinders by slowing down the air speed inside the plenum chamber. As a result there is less of a pressure drop inside the plenum chamber between cylinders, and less air momentum, resulting in better air distribution and power. The change in airflow characteristics is shown in the diagram below.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-textformat='{\"td\":\"none solid rgb(0, 0,
