3.5 Inches Intake Manifold Cummins 6.7L Dodge Ram 2500/3500 07-18

The 3.5-inch Intake Manifold for the 6.7L Cummins (Dodge Ram 2500/3500 2007-2018) is a performance upgrade designed to improve airflow and engine efficiency. Here’s a breakdown of its key features and considerations:

Key Features:

• Increased Airflow: The larger 3.5″ diameter improves airflow compared to the stock manifold, enhancing turbo spool and overall engine performance.

• Emissions Delete Required: This manifold does not support factory emissions equipment (EGR, heater grid, etc.), meaning you’ll need a full emissions delete for installation.

• Off-Road Use Only: Since it removes emissions components, this part is not legal for on-road use in states/countries with emissions compliance laws.

• Powder Coating Options: Available in select colors for an additional charge (e.g., black, red, or other custom finishes).

• Compatibility: Works best when paired with:

  • Pusher 3.5″ Intercooler Tubes (for a full upgraded intake path).

  • CNC-machined Heater Grid Delete (to fully eliminate the stock intake heater).

Installation Notes:

• Tuning Required: Since this deletes emissions components, you’ll need a custom tune to prevent check engine lights and ensure proper engine operation.

• Performance Gains: Best suited for modified 6.7L Cummins engines running higher boost levels, aftermarket turbos, or compounds.

• Legal Considerations: Confirm local laws before installing—emissions deletes are illegal for on-road use in the U.S. under federal EPA regulations.

Who Should Buy This?

• Drag Racers / Sled Pullers looking for maximum airflow.

• Off-Road / Competition Use where emissions compliance isn’t required.

• High-Performance Builds with supporting mods (bigger turbo, fuel system upgrades, etc.).
