Cold Air Intake W/Heat Shield Dodge Ram (2003-2007) 2500 3500 5.9 L6 Diesel Engine Red

Advanced Induction for the 5.9L Cummins 24V Diesel

Who It’s For: Engineered for Dodge Ram owners running the 5.9L Cummins 24V powerplant who are tired of the stock sluggishness and slow turbo spool-up during heavy hauling.

The Symptom: The factory intake on the 5.9L Cummins is designed for silence, not performance. It uses a restrictive, enclosed plastic resonator box and accordion-style rubber tubing that creates massive air turbulence. This turbulent air tumbles through the intake tract, causing the turbocharger to work harder just to pull in a breath of air. For a heavy-duty truck, this results in a sluggish throttle response and higher Exhaust Gas Temperatures (EGTs) when you’re trying to get a heavy trailer moving or merging onto the highway.

The Engineering Fix: This system replaces that restrictive OEM plumbing with a high-flow, mandrel-bent T-304 aluminum tube. By smoothing out the airflow path and eliminating the internal baffles, we significantly reduce skin friction and air resistance. The included powder-coated steel heat shield isolates the washable cone filter from the radiant heat of the engine bay. This ensures that the air entering your turbo is as dense as possible, allowing for a more efficient combustion cycle and a much faster turbo spool.

Why Mechanics Choose This Kit

• Substantial Power Gains: Expect a 7-10% increase in horsepower and a 6-8% bump in torque. On the 5.9L Cummins, this translates to better low-end grunt and more confident towing capacity.
• Defined Induction Sound: Replacing the plastic baffles allows the natural mechanical roar of the engine and the high-pitched whistle of the turbocharger to be heard clearly under acceleration.
• Superior Build Quality: Constructed from lightweight, polished T-304 aluminum and paired with a reusable, washable high-flow filter that eliminates the need for paper filter replacements.
