2015-2016 Ford 6.7L Power Stroke Zilla Intake Manifold and Turbo Inlet Kit

Intake Manifold and Turbo Inlet Kit

The stock cast aluminum intake manifold on the Ford 6.7L Power Stroke is a well-known performance bottleneck. Certain design characteristics of the stock manifold restrict fresh air intake, which is particularly unfavorable for engine performance. Some sections of the stock manifold’s internal passage are even narrower than a 2.5-inch-diameter tube, severely limiting airflow. Additionally, the EGR inlet swirl is positioned directly in the center of the flow path, creating significant turbulence and flow disruption. This turbulence reduces both the intake air velocity and the volume of air entering the cylinder heads.

The PPE Performance Intake Manifold effectively eliminates these stock bottlenecks by utilizing large 3.25-inch stainless steel tubing, combined with hydroformed runners that seamlessly direct even airflow into both cylinder heads. The restrictive EGR boss has been eliminated, creating unobstructed flow path. Furthermore, the EGR inlet port has been carefully repositioned and angled to ensure even distribution of fresh air and EGR gases to both banks, maximizing volumetric efficiency. To support the repositioned EGR inlet, the kit includes a redesigned stainless steel EGR pipe and new EGR gaskets. With these enhancements, the PPE Performance Intake Manifold achieves a 69% higher maximum flow rate than the stock component.

On the turbo inlet side, our system features a four-inch stainless steel turbo inlet, paired with a dry-carbon-fiber airbox duct. Unlike the stock components that transition from round to oval and then back to round shape, both of the PPE components maintain a fully round shape and 4-inch diameter. This ensures higher flow efficiency and reduces frictional losses. Additionally, the factory plastic two-chamber turbo resonator has been removed, reducing air turbulence and weight, while enhancing turbo sound. The best part of this kit is its hassle-free installation and OEM-like fitment. All stock mounting points - including sensor clips, dipstick brackets, and coolant hose connections - are retained. Not a single wiring harness or coolant line is left hanging, and the manifold absolute pressure (MAP) sensor port is at the exact same location as the stock manifold.
