This can create uneven clamping pressure, leading to warped manifolds, broken studs, failed gaskets, exhaust leaks, and lost performance. The KC Turbos Upgraded Exhaust Manifolds solve this with a redesigned high-silicon molybdenum cast iron manifold that uses all 11 stud locations for a stronger, more even seal. KC also redesigned and port-matched the runners to increase flow by over 30% compared to stock, helping reduce back pressure and improve turbo efficiency. With thicker mounting flanges, a re-engineered turbo mounting face, a larger machined sealing surface, and included stainless steel studs and spacers, this kit is built as a long-term fix for common EcoBoost manifold failures while supporting better reliability and performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e 302656\u003c\/p\u003e\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e30% CFM Increase over Stock Manifolds\u003c\/li\u003e\n\u003cli\u003ePort Matched Exhaust Manifold Runners\u003c\/li\u003e\n\u003cli\u003e75% Thicker Manifold Flange \u003c\/li\u003e\n\u003cli\u003eUtilizes 3 additional exhaust stud locations for better seal\u003c\/li\u003e\n\u003cli\u003eCast with high silicone molybdenum to prevent warping under extreme heat\u003c\/li\u003e\n\u003cli\u003eUpgraded Stainless Steel Exhaust Manifold Studs with integrated Hex installation\u003c\/li\u003e\n\u003cli\u003ehead for easy installation\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eIncludes\u003c\/h6\u003e\n\u003cp\u003eNew Studs, Spacers, Nuts, and MLS Gaskets\u003c\/p\u003e\n\u003ch6\u003eOE Part Number exchange\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003eReplaces Ford OEM Part Numbers: \u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBL3Z-9430-B\u003c\/li\u003e\n\u003cli\u003eBL3Z-9430-D\u003c\/li\u003e\n\u003cli\u003eBL3Z-9431-B\u003c\/li\u003e\n\u003cli\u003eBL3Z-9431-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KC Turbos","offers":[{"title":"Default Title","offer_id":53749189935472,"sku":"302656","price":561.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2084\/8209\/files\/KC3.5Exhaustmanifolds.webp?v=1778771273","url":"https:\/\/www.dirtydieselcustom.ca\/products\/2011-2016-ecoboost-3-5l-upgraded-exhaust-manifold-302656","provider":"Dirty Diesel Customs","version":"1.0","type":"link"}
