On Radium's 13B-REW secondary rail, the 11mm height specifically suits the Xcessive Manufacturing 4-port intake manifold, while other installations select spacer height to set rail standoff per the injector geometry. Count one spacer per mounting point and order accordingly.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x 11mm phenolic insulating spacer (14-0711)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRadium fuel rail installations using 11mm spacer height (incl. 13B-REW secondary rail on Xcessive 4-port manifolds)\u003c\/li\u003e\n\u003cli\u003eCustom rail installs needing thermal isolation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672700715075,"sku":"14-0711","price":9.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-14-0711-29454204731462_e6a69207-a1a2-4e01-810e-bcfa3178f8cc.jpg?v=1786717232","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-insulating-spacer-11mm-universal-14-0711","provider":"Tuned by Shawn","version":"1.0","type":"link"}
