BD Diesel 1043005 Exhaust Manifold Passenger Side 6.7L Power Stroke Ford 2011-2016

The BD Diesel 1043005 exhaust manifold is engineered to solve one of the most common failure points on 6.7L Power Stroke diesel engines. This passenger side replacement manifold is constructed from high-silicon ductile cast iron with heavy-duty 0.275-inch thick walls—75% thicker than stock—to resist cracking under extreme exhaust temperatures and thermal cycling.

Designed using computational fluid dynamics, this manifold delivers an average flow increase of 9.3% over OEM (189 cfm/port vs. 173 cfm/port stock), improving exhaust efficiency while maintaining full EGR compatibility. The machined bolting flanges are significantly thicker than factory components for improved sealing and durability.

Each manifold includes the longest exhaust studs available that fit across all 8 cylinders, plus black oxide-coated spacers to enhance thermal durability and prevent stud failure. The manifold features a high-temperature POR-15 black coating for corrosion resistance and professional appearance.
