Receive performance and durability with our enhanced Ford 3.5L EcoBoost exhaust manifolds, specifically designed for the 2017-2020 model years. Our BD upgraded manifolds address common exhaust manifold bolt failures by incorporating two additional bolt holes and by utilizing extended fasteners and spacers to better withstand thermal expansion. In addition, we've engineered them to flow 16% better than the OEM to increase efficiency. Crafted with precision, our BD Manifolds boast a robust, thicker design. They are constructed from high-silicon ductile iron to combat warping, ensuring your vehicle remains at peak performance for the long haul.
