FITMENT
- 2007.5–2010 6.7L Dodge Ram Cummins 2500 3500 Turbo Diesel.
- 2011–2018 6.7L Ram Cummins 2500 3500 4500 5500 Turbo Diesel.
DESCRIPTION
Product Overview
- The factory intake horn on the 6.7L Cummins is restrictive, with sharp bends and narrow passages designed to accommodate emissions hardware rather than optimal airflow.
- Replacing it with the 3.5" High-Flow Intake Manifold Elbow creates a smoother, larger airflow path between the intercooler and intake manifold, helping reduce intake restriction and improve airflow distribution.
Key Features
- T304 Stainless Steel Construction: TIG-welded stainless steel prevents cracking, flexing, or melting under high boost and engine bay heat.
- Faster Turbo Spool & Throttle Response: Reduces intake restriction to eliminate turbo lag and deliver instant throttle response when you hit the pedal.
- Lowers EGTs: Better cylinder air filling results in more efficient combustion, dropping EGTs by 50°F to 200°F under heavy loads and towing.
- Airflow Improvement: Replaces the restrictive factory intake horn with an expanded 3.5" mandrel-bent pathway to reduce air turbulence and boost loss.
FAQ
Q: What does a 3.5" High-Flow Intake Manifold Elbow do?
A: The 3.5" High-Flow Intake Manifold Elbow replaces the restrictive factory intake horn with a smoother, larger airflow path. It helps reduce intake restriction and improves airflow efficiency for better engine response.
Q: Do I need to remove my factory grid heater to install this?
A: No. This intake elbow is designed to work with the factory grid heater or aftermarket grid heater delete plate setups. You can keep your original grid heater for reliable cold-weather starting or remove it for a higher-flow intake configuration.
Q: What are the NPT ports used for?
A: The integrated NPT ports can be used for installing aftermarket sensors, such as boost pressure monitoring equipment, depending on your setup.
Q: Will this work with an EGR delete kit?
A: Yes, In fact, it is the ideal companion to an EGR delete kit. Installing them together completely cleans up your intake track, blocks hot recirculated exhaust gas, and unlocks the maximum possible airflow into your cylinders.
Q: Do I need an IAT sensor extension harness when installing this 3.5" intake horn?
A: Yes, Installing this high-flow 3.5" intake horn may require relocating the factory IAT sensor from its original position. Since the OEM harness is short and rigid, the IAT Extension Harness provides extra length for a secure plug-and-play connection without stretching, cutting, or modifying factory wiring.
