High Flow Intake Manifold for Ford F-250 F-350 F-450 F-550 (2015-2016) 6.7L Diesel

Cast Aluminum High-Flow Intake Manifold for 2015-2016 Ford F-250, F-350, F-450, F-550 (P473)

What it Does: The high-flow cast aluminum intake manifold replaces the brittle OEM composite intake on 2015-2016 Ford Super Duty trucks to eliminate boost leaks, optimize charge air distribution, and handle elevated manifold absolute pressures.

The Stock Ford F-250, F-350, F-450, F-550 Plastic Manifold Failure

Factory P473 platform trucks equipped with the 6.7L Power Stroke Scorpion utilize a multi-piece molded plastic intake manifold. Over extended duty cycles and high exhaust gas recirculation (EGR) thermal loading, the factory composite structure experiences heat soak, polymer embrittlement, and seam separation along the vibration-welded joints. High boost spikes common in towing applications distort the plenum walls, resulting in unmetered boost loss, elevated exhaust gas temperatures (EGTs), and degraded volumetric efficiency across the cylinder banks.

The Engineering Solution

Engineered as a rugged mechanical upgrade, this assembly is cast from high-grade aluminum alloy to withstand high boost pressures and extreme underhood thermal stress. The two-piece plenum design features smoothed internal runners with enlarged cross-sectional radiuses to streamline charge airflow and eliminate factory directional restrictions. It includes a vehicle-specific turbo oil feed line matched precisely to the 2015-2016 GT37 turbocharger oil routing, preventing oil starvation and installation mismatch. The assembly retains factory sensor provisions and secures with heavy-duty silicone coupler boots and hardware to guarantee an airtight seal under load without requiring PCM recalibration.
