BD Diesel 1043007 Exhaust Manifold Kit, Hi-Silicon Ductile Iron, 50-State Legal

The BD Diesel 1043007 exhaust manifold kit targets one of the common failure points on the Ford 6.7L Power Stroke: cracked exhaust manifolds. It is cast from high-silicon ductile iron with a 0.275 inch wall, which BD states is 75 percent thicker than stock, to resist cracking from high exhaust temperatures.

Key Features:

• High-silicon ductile cast iron with 0.275 inch thick walls that retain heat and help prevent warping
• Machined, thicker bolting flanges
• Longer exhaust studs for improved thermal durability
• Includes the longest stud and spacer kit that fits across all 8 cylinders; thick spacers are black oxide coated
• Average flow increase of 9.3 percent (OEM average 173 cfm/port, BD average 189 cfm/port)
• Designed using computational fluid dynamics
• Gaskets included: exhaust manifold, cross-over tube and EGR port
• Fully EGR compatible

Emissions and Certification:

• Covered under CARB EO No. D-553-17 and legal for sale and use in all 50 states
• SEMA Certification No. SC-BDD01-0050

Additional Information:

• Replaces OEM part numbers DC3Z9430A (right side) and DC3Z9431A (left side)
• Estimated install time: 9 hours
• Trucks using the MPD budget SXE turbo kit must use part number 1043006 with an OEM passenger side manifold

A durable, emissions-compliant replacement for owners who want reliable exhaust manifolds on their 6.7L Power Stroke.
