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\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0901\/5509\/0290\/files\/plenum_daigram.jpg?v=1773642390\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNot only will our spacer help you make more power, it will also help prevent any costly rebuilds through dangerous lean outs that occur with standard manifolds in high horsepower\/boost applications (due to poor air distribution).\u003c\/p\u003e\n\u003cp\u003eIn addition to improving air distribution between cylinders, the increase in plenum volume also has a positive effect on bottom end torque.\u003c\/p\u003e\n\u003cp\u003eThe fact these spacers are manufactured from the same thermal resistant composite material as our manifold insulators means further horsepower gains are possible due to the reduction in heat soak.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eKey benefits:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesign registered.\u003c\/li\u003e\n\u003cli\u003eReduces charge air temperature resulting in better power consistency and detonation prevention.\u003c\/li\u003e\n\u003cli\u003ePower increase with no undesirable side effects.\u003c\/li\u003e\n\u003cli\u003eImproved air distribution between each cylinder.\u003c\/li\u003e\n\u003cli\u003eImproved fuel economy.\u003c\/li\u003e\n\u003cli\u003eEasy to install.\u003c\/li\u003e\n\u003cli\u003eCan be used as a replacement gasket.\u003c\/li\u003e\n\u003cli\u003eReusable.\u003c\/li\u003e\n\u003cli\u003eProven gains at an affordable price.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eContents:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e01 XPlenum spacer\u003c\/li\u003e\n\u003cli\u003e01 X Silicone gasket maker\u003c\/li\u003e\n\u003cli\u003e04 X Spacer bush\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eVehicle Fitment Guide\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg alt=\"VFG_MI805\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0901\/5509\/0290\/files\/MI805-VFG.jpg?v=1762935654\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003e\u003cstrong\u003eNote: \u003c\/strong\u003e\u003c\/span\u003eInstallation is very straight forward, requiring only the removal of your plenum cover to install the plenum spacer.\u003c\/p\u003e","brand":"MACE","offers":[{"title":"Default Title","offer_id":45983041192132,"sku":"MI805","price":130.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/8928\/4292\/files\/MI805-Updated-Image.png?v=1774433994","url":"https:\/\/maceengineering.com.au\/products\/mace-performance-635mm-plenum-spacer-to-suit-ford-falcon-ba-bf-fg-boss-260-290-54l-v8","provider":"Mace Engineering Group","version":"1.0","type":"link"}
