BD Diesel 11-16 Ford F-150 3.5L Ecoboost Exhaust Manifold Passenger Side

The factory exhaust manifold on your 2011-2016 Ford F-150 with the 3.5L EcoBoost engine has a known issue where it doesn't use all the available stud locations on the cylinder head. This often leads to warped manifolds, broken studs, and blown gaskets. BD Diesel has addressed this by designing a manifold that utilizes all 11 stud locations, just as it should have come from the factory. This improved design helps prevent the common warping and stud breakage problems you might be experiencing.

This manifold is constructed from thick-walled, high-silicon ductile iron, a material chosen for its resistance to thermal warping. BD includes new, longer 8.8-grade studs and spacers with this manifold, ensuring a solid connection and further enhancing its durability. This is a well-built replacement that aims to solve the inherent design flaw in the original equipment.

When installing, consider BD Diesel's optional 1043002 parts kit, which can make the job smoother. This manifold replaces Ford OEM part numbers BL3Z-9431-B and BL3Z-9431-D.
