Upgraded Exhaust Manifold & Gasket Kit For 2011-2016 Ford F-150 3.5L Ecoboost

The 2011-2016 Ford 3.5L EcoBoost suffers from a factory design flaw—the OE manifold uses only 8 of 11 available stud locations, causing warped manifolds, broken studs, and blown gaskets. This upgraded manifold corrects that oversight by utilizing all 11 stud positions for superior clamping force and reliability. Constructed from thicker-walled 304 stainless steel, it resists thermal warping while improving exhaust flow characteristics. The complete kit includes 22 exhaust spacers and fasteners, delivering the durability and performance Ford should have engineered from the start.
