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. This, in turn, feeds each intake runner more evenly improving throttle response and bottom end torque.\u003c\/p\u003e\n\u003cp\u003eThe change in airflow characteristics is shown in the diagram below.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0901\/5509\/0290\/files\/Plenum-Spacer-Draft-Image.jpg?v=1768470125\" alt=\"\"\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNot only will our spacer help you make more power, it will also reduce air-fuel ratio variance between cylinders due to improved air distribution between cylinders.
