The cylinder head on Fords 3.5L Gas Ecoboost has threaded holes for 11 exhaust studs to be used, however the OE manifold only utilizes 8 of those stud locations. BD has designed a manifold that not only utilizes all 11 stud locations, but also improves exhaust flow and has improved durability, the way it should have come from the factory. BD's Ford 3.5L exhaust manifolds are made from thicker-walled high silicone ductile iron designed to resist thermal warping. Each kit includes 22 exhaust spacers and 22 class 8.8 studs designed to further improve thermal durability.\u003c\/p\u003e\n\u003cdiv class=\"title-hr\"\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cdiv class=\"metafield-rich_text_field\"\u003e\n\u003cul\u003e\n\u003cli\u003e50-STATE LEGAL!\u003c\/li\u003e\n\u003cli\u003eAverage flow increase of 25.9% (OEM avg 110cfm\/port BD avg 139cfm\/port)\u003c\/li\u003e\n\u003cli\u003eUtilize 3 additional exhaust stud locations\u003c\/li\u003e\n\u003cli\u003eBD Thick wall high-silicon ductile cast iron resists thermal warping\u003c\/li\u003e\n\u003cli\u003e15mm longer exhaust studs + spacers\u003c\/li\u003e\n\u003cli\u003eNew studs, spacers, and nuts included\u003c\/li\u003e\n\u003cli\u003eReplaces Ford OEM part numbers: BL3Z-9430-B, BL3Z-9430-D, BL3Z-9431-B, BL3Z-9431-D\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"1396\" height=\"785\" src=\"https:\/\/www.youtube.com\/embed\/z-dKChPKpDg\" title=\"FORD F150 Manifold Replacement - How to Fix FORD's Own DUMB Mistakes!\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BD Diesel","offers":[{"title":"Default Title","offer_id":46888267088121,"sku":"BDD1043001","price":418.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5428\/0953\/files\/f1f0f2d494af4bf734a056d8d12b8b70.jpg?v=1758798980","url":"https:\/\/octanehaus.com\/products\/bd-diesel-exhaust-manifold-set-ford-f-150-3-5l-ecoboost-11-16","provider":"Octane Haus","version":"1.0","type":"link"}
