2007.5-2012 6.7L Dodge Ram 2500 3500 Cummins Diesel.
DESCRIPTION
Product Overview
- The 6.7L Cummins ISB I6 Turbo Diesel engine introduced in 2007.5 delivers exceptional low-end torque and towing capability for Ram trucks. However, the factory plastic intake system uses narrow, restricted ducting and noise-baffling chambers that restrict airflow into the turbocharger, increasing EGTs and causing power lag during heavy towing.
- The High-Flow Performance Cold Air Intake System replaces the stock intake assembly with a smooth, high-velocity mandrel-bent aluminum tube and a high-efficiency reusable dry air filter. By feeding cooler, unrestricted air directly into the Holset turbocharger, this kit reduces EGTs, sharpens throttle response, and unleashes the aggressive turbo spool whistle of the 6.7L Cummins.
Key Features
- High-Flow Mandrel-Bent Tubing: Replaces restrictive factory piping with a smooth aluminum tube to maximize CFM air volume and velocity into the turbocharger.
- Open-Element High-Flow Design: Eliminates restrictive factory airbox baffles to maximize surface area exposure and pull in ample ambient air.
- Washable Dry Air Filter: High-flow, reusable filter element provides superior filtration efficiency without requiring messy oil treatments.
- Lowers Exhaust Gas Temperatures: Feeding dense, oxygen-rich air improves combustion efficiency, actively reducing EGTs during heavy towing.
- Aggressive Turbo Spool Sound: Removes factory sound mufflers to unleash a crisp turbo whistle and responsive induction roar under acceleration.
FAQ
Q: Do I need a custom tuner or ECU reflash after installing this cold air intake?
A: No, custom tuning is not required. The intake operates safely within your 6.7L Cummins factory parameters, though pairing it with an aftermarket tuner will yield even greater horsepower and torque gains.
Q: How does this intake kit help when towing heavy trailers?
A: By delivering a higher volume of dense, oxygen-rich air to the turbocharger, fuel burns more completely. This increases working torque on steep highway inclines while actively keeping Exhaust Gas Temperatures down.
Q: What are the main performance benefits of upgrading to this 6.7L Cummins intake?
A: The factory airbox heavily restricts intake volume under high boost. Upgrading to this high-flow system increases air velocity and volume into the turbo, resulting in faster spool times, reduced turbo lag, lower EGTs, and improved throttle response.
Q: What is the recommended method to wash the high-flow dry filter without damaging it?
A: Tap out loose dust, submerge or rinse the filter gently using warm water and mild household soap from the inside out (clean side to dirty side), rinse thoroughly with low-pressure tap water, and let it air dry completely before reinstalling—never use compressed air, hairdryers, or heat guns.
