Intake Manifold Elbow & Grid Heater Plenum for Dodge RAM (2007-2024) 6.7L Turbo Diesel

High-Flow Intake Manifold Elbow & Grid Heater Plenum for 2007-2024 Dodge, RAM Ram 2500, 2500, Ram 3500, 3500

Direct replacement 3.5-inch stainless steel intake manifold upgrade designed to outflow the restrictive factory casting and eliminate grid heater bottlenecks.

The Stock 2007-2024 Dodge, RAM Ram 2500, 2500, Ram 3500, 3500 Flow Restriction

The factory cast intake manifold and grid heater on the 2007.5-2024 6.7L Cummins suffer from severe aerodynamic limitations and thermal inefficiency. The OEM grid heater element sits directly in the path of forced induction from the turbocharger, creating excessive turbulence and pressure drops before the charge air even reaches the cylinders. Additionally, the rough interior surface of the cast factory elbow creates boundary layer drag that drastically impedes CFM (cubic feet per minute) flow. This bottleneck results in higher exhaust gas temperatures (EGTs), sluggish turbo spool times, and effectively chokes the engine under heavy load or high-boost towing applications.

The Engineering Solution

This upgraded 3.5-inch maximum flow intake manifold completely re-engineers the intake pathway. Constructed from mandrel-bent, polished stainless steel, it guarantees a smooth, unrestricted interior surface that prevents boundary layer separation and minimizes turbulence. By deleting the restrictive OEM grid heater block and transitioning to a wide-open plenum design, cold-side charge air velocity is drastically increased. The assembly features a precisely engineered clearance indentation designed specifically to safely bypass the No.1 high-pressure injector line without compromising internal flow dynamics. Furthermore, the MAP sensor mounting location has been strategically relocated to the underside of the manifold, providing a cleaner engine bay aesthetic while maintaining highly accurate manifold absolute pressure readings directly in the charge air stream.
