FITMENT
- 1994–1998 5.9L Dodge Ram Cummins 2500 3500 12V Turbo Diesel.
- NOTE: Fits 12-Valve (12V) 5.9L Cummins ONLY (1994 to mid-1998).
- Does NOT fit 24-Valve (24V) 5.9L engines (mid-1998.5–2002) or 6.7L engines.
DESCRIPTION
Product Overview
- The legendary 5.9L 12V Cummins is built for extreme durability, but the restrictive factory cast intake elbow introduces heavy turbulence and flow bottlenecks right before the manifold—limiting performance under heavy towing and high-boost applications.
- Engineered to open up incoming charge air, this 3" Intake Elbow Charge Pipe Kit replaces the choked stock unit with a smooth, mandrel-bent 6061-T6 aluminum pipe. Its precision-contoured, sweep-radius geometry optimizes intake airflow, accelerates turbo spoolup, and bolts directly to the factory intake heater flange for a seamless, heavy-duty upgrade.
Key Features
- Heavy-duty 6061-T6 aluminum construction with precision TIG-welded seams and reinforced mounting flanges built to handle sustained high boost
- Smoothes intake air delivery to reduce turbo lag and sharpen throttle response across the RPM range
- Helps keep EGTs in check under sustained load by improving combustion air supply to the cylinders
- Retains the OEM grid heater flange — no need to delete or relocate factory cold-start components
- Complete kit with silicone coupler, T-bolt clamps, and all mounting hardware included
FAQ
Q: Will this 3" intake elbow fit my 1998.5-2002 24V Cummins?
A: No. This elbow is engineered specifically for the 1994-1998 12V 5.9L Cummins intake horn pattern. The 1998.5+ 24V engines use a completely different intake horn bolt pattern and mounting configuration. Check our store for 24V-compatible intake upgrades.
Q: How does this compare to the factory intake elbow in terms of airflow?
A: The OEM cast elbow has an irregular shape with the narrowest cross-section measuring approximately 1.5". Our 3" mandrel-bent elbow maintains a consistent full-diameter flow path from end to end, eliminating the bottleneck that chokes turbo efficiency.
Q: Do I have to remove my factory grid heater to install this?
A: No. The elbow bolts directly to the OEM intake heater flange, so your factory grid heater stays fully functional for cold starts.
Q: Looking for a larger intake upgrade for a more heavily modified 12V?
A: If you’re running a larger turbo or high-performance fueling, check out our 3.5" Air Intake Elbow for 1994-1998 12V Cummins for even greater airflow volume.
