{"title":"Intake Manifolds | 2025-2026 Ram 6.7 Cummins","description":"\u003cp\u003eOn 6th-generation Cummins engines, the stock intake manifold is designed to meet strict emissions and noise requirements, but its angular runner layout and limited plenum volume can create turbulence and airflow bottlenecks before air ever reaches the cylinders. That restriction can slow turbo response, reduce throttle sensitivity, and contribute to higher exhaust gas temperatures when towing or hauling.\u003c\/p\u003e\n\u003cp\u003eUpgrading to a high-flow intake manifold for your 6.7L Cummins Ram HD improves airflow distribution and increases overall intake volume, helping the turbo operate more efficiently for faster spool-up, stronger low-RPM torque, and cooler EGTs under load. Many aftermarket manifolds also include multiple pre-tapped ports, making it easy to install a boost gauge, or add nozzles for water-methanol injection, nitrous, or propane systems without custom fabrication; perfect for performance-focused Ram 2500 and Ram 3500 owners.\u003c\/p\u003e\n\u003cp\u003eAnd besides the purely functional attributes of these manifolds, how about the pure intention for them to look good! There is always something to be said for popping the hood of your Cummins and having a well dressed out engine compartment, as opposed to a dark, oil stained cavity that seeks attention.
