Open spacers increase plenum volume and move the throttle blades away from the roof of the runners, allowing the air\/fuel mixture to turn more easily into the runners for improved distribution and mixture quality. Open spacers will add mid range and top end hp. Wilson Manifolds is the only manufacturer to produce open spacers in thicknesses from 1\" to 2\" in 1\/8\" increments for 4150 carburetors for precise tuning and for applications where hood clearance is at a premium. The engine builder spacer kit includes all nine open spacers (4150) in 1\/8\" increments and is a must have for any dyno room and for track tuning.\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Adds mid \u0026amp; top end power\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Increase plenum volume\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Allows the air\/fuel mixture to turn more easily into the runners by moving the carburetor up away from the runner roofline\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Improved distribution and mixture quality\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Will add mid range and top end hp\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* 1\" to 2\" Heights in 1\/8\" increments for 4150 carburetors\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* Wilson Manifolds is the only manufacturer that offers multiple heights for 4500 carburetors\u003c\/span\u003e\u003cbr style=\"-webkit-font-smoothing: antialiased; -webkit-tap-highlight-color: transparent; color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e\u003cspan style=\"color: rgb(51, 55, 69); font-family: Ubuntu; font-size: 13px; background-color: rgb(244, 244, 244);\"\u003e* 4150 spacers are designed to pass NASCAR No-Go Gauges\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Wilson Manifolds","offers":[{"title":"Default Title","offer_id":44472509726785,"sku":"020010","price":144.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/2500\/9217\/files\/020010_1INCH_OPEN_LIGHTWEIGHT_SPACER_4500_01_WILSON_MANIFOLDS-800x800.jpg?v=1787635186","url":"https:\/\/www.theefistore.com\/products\/wsn-020010","provider":"The EFI Store","version":"1.0","type":"link"}
