BD Diesel Exhaust Manifold Passenger Side is specifically designed to resolve a structural issue in the 2011–2016 Ford 3.5L EcoBoost engine. The original factory manifold only secures to 8 of the 11 available exhaust stud locations in the cylinder head, which often leads to warping, broken studs, and gasket leaks due to uneven pressure and heat. BD’s manifold is engineered to utilize all 11 studs, ensuring a more secure and balanced fit, which enhances both exhaust flow and durability. Made from thick high-silicone ductile iron, it withstands high temperatures and resists thermal distortion, contributing to consistent engine performance. The kit includes 11 exhaust spacers and class 8.8 studs, further improving thermal resistance and structural integrity. Designed for the 2011–2016 Ford F-150 3.5L EcoBoost, this manifold offers a more durable and efficient alternative to the factory design, supporting better engine performance and reliability.
