Fits select 2011-2023 Ford F-150, Expedition, Transit-150/250/350, and Lincoln Navigator (3.5L). This BD Diesel passenger side exhaust manifold is engineered to address the common thermal warping and cracking issues found in factory manifolds. Cast from thick-walled, high-silicon ductile iron, this manifold provides superior heat management and structural integrity under high-performance or heavy towing conditions.

• Replaces Ford OEM part numbers: BL3Z-9431-B, BL3Z-9431-D
• High-silicon ductile cast iron construction resists thermal warping
• Utilizes 3 additional exhaust stud locations for improved head-to-manifold sealing
• Includes 15mm longer exhaust studs, spacers, and nuts for secure installation
• Manufacturer Part Number: 1043004

By utilizing additional mounting points and more robust hardware, this manifold ensures a more consistent seal and a longer service life than the original equipment. For an even more streamlined installation, the optional 1043002 addition parts kit is recommended.
