• 2007-2018 Dodge Ram 2500 3500 6.7L Diesel

Description

Maximize airflow, lower EGTs, boost fuel economy, and unlock your 6.7L Cummins’ true performance with the SPETUNER 3.5" High-Flow Intake Manifold.

Why Upgrade Your Intake Manifold?

The factory intake manifold creates airflow restrictions, raises EGTs under load, and limits power potential—especially when towing or modified. Replacing it with a high‑flow performance manifold:

• Eliminates bottlenecks for smoother, denser airflow
• Lowers exhaust gas temperatures to protect your engine
• Improves combustion efficiency for better MPG
• Boosts throttle response and turbo spool
• Adds reliable power and torque for heavy‑duty use

Features

• 2 NPT ports
• 0.5-1 MPG increase
• 50-200 degrees F drop in EGT's
• Unobstructed 3.5" inlet to two 3" mandrel bent tubes
