High Flow Intake Manifold For Ford F250 F350 F450 F550 Super Duty (2011-2019) 6.7L PowerStroke Diesel

High-Flow Cast Aluminum Intake Manifold for 2011-2019 Ford F-250, F-350, F-450, F-550 (6.7L Scorpion / P473)

What it Does: Replaces the restrictive and failure-prone factory plastic intake manifold with a heavy-duty cast aluminum two-piece unit to increase airflow, reduce EGTs, and eliminate the risk of plenum cracking under high boost.

The Stock F-250, F-350, F-450, F-550 Plastic Manifold Weakness

The OEM intake manifold on the 2011-2019 Ford 6.7L PowerStroke is constructed from a composite plastic that is inherently susceptible to thermal fatigue. Over time, the repeated heat cycles of the diesel engine, combined with high-boost pressures from the turbocharger, cause the plastic to become brittle and eventually crack, leading to significant boost leaks and power loss. Furthermore, the factory design prioritizes ease of manufacturing over laminar flow. The internal geometry features restrictive transitions and rough surfaces that create air turbulence, which increases intake air temperatures and forces the turbocharger to work harder to maintain target manifold absolute pressure (MAP), ultimately hindering volumetric efficiency and throttle response.

The Engineering Solution

This Doctor Diesel USA intake manifold is engineered from high-grade cast aluminum, providing a permanent mechanical solution to the structural deficiencies of the factory unit. By moving to a two-piece aluminum construction, this manifold can withstand extreme boost levels without the risk of expansion or bursting. The internal runners have been precision-cast with smoothed transitions to maximize CFM (Cubic Feet per Minute) delivery directly to the cylinder heads. This reduction in intake restriction allows for lower Exhaust Gas Temperatures (EGTs) and faster turbo spool-up during heavy towing or high-load scenarios. The kit is designed for a direct bolt-on installation, featuring integrated mounting brackets and hardware that maintain OEM sensor locations, ensuring a clean engine bay and professional-grade fitment without requiring any PCM recalibration or aftermarket tuning.

Common Questions

Will this fit my 2018 F-350 6.7L?
Yes. It fits 2011-2019 Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke.

Does it fit a 2015 or 2016 truck?
Yes. It fits every 2011-2019 6.7L Powerstroke Super Duty, including 2015 and 2016.

What is it made of?
Two-piece cast aluminum from Doctor Diesel USA, with smoothed runner transitions.

Why replace the factory manifold?
The stock plastic manifold gets brittle from heat cycles and boost and can crack, causing boost leaks. Cast aluminum handles high boost without that risk.

Will it help EGTs?
Yes. The smoother, freer-flowing runners move more air into the engine, which helps bring exhaust gas temperatures down.
