FITMENT
- 1994–1998 5.9L Dodge Cummins Ram 2500 3500 Turbo Diesel.
- Note: Fits 12-Valve P-Pump models only. Will not fit 24-Valve 1998.5+ models.
DESCRIPTION
Product Overview
- The small, restrictive factory intake horn on the 5.9L 12V Cummins severely limits intake airflow under demanding conditions. When pulling heavy loads or running higher boost levels, this tight stock entry point starves the engine of fresh air, causing sluggish throttle response and dangerous EGT spikes.
- Upgrade to this 3.5" High-Flow Intake Elbow to clear the air path and smooth out internal airflow. By feeding cooler, high-density charge air directly into your intake manifold, it sharpens turbo spool times, promotes cleaner fuel burn, and protects your engine from excessive heat buildup.
Key Features
- T304 stainless steel construction with heavy-duty TIG welds engineered to endure sustained high-boost pressures, repeated heat cycling, and severe engine vibration without cracking or warping.
- Accelerates turbo spool by eliminating intake-side turbulence with smooth inner walls that allow boost to build faster and hit harder.
- Drops EGTs under load — improved intake airflow promotes more complete combustion, helping reduce exhaust gas temps during towing and high-output conditions.
- The larger 3.5" flow path is sized to support upgraded single turbos and compound configurations.
- Complete installation kit with silicone coupler, T-bolt clamps, L-shape mounting bracket, and stainless hardware.
FAQ
Q: Can I install this 3.5" elbow on a completely stock 12V Cummins?
A: Yes. It works as a direct bolt-on airflow upgrade even on an otherwise stock truck. That said, the 3.5" sizing really shines when paired with turbo, exhaust, or fueling modifications that can take advantage of the increased flow capacity.
Q: Will I notice faster turbo response after installing this?
A: Absolutely. By removing the intake restriction and improving airflow efficiency through the intake tract, this elbow helps the turbo build boost more quickly. The effect is especially noticeable on modified or heavily loaded trucks where the factory bottleneck becomes most pronounced.
Q: Does this kit replace the factory intake horn and charge pipe entirely?
A: Yes. The entire restrictive factory intake elbow and charge pipe assembly gets replaced with the larger high-flow design, eliminating the factory bottleneck from the intercooler outlet all the way to the intake plenum.
Q: Is tuning required after installation?
A: No tuning is required for this airflow upgrade. It bolts on and works immediately. For the best results, however, many owners pair it with supporting mods like a cold air intake and free-flowing exhaust.
