4th Gen 6.7L Cummins Air Intake

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins Performance Cold Air Intakes & Filters

Lower your exhaust gas temperatures (EGTs), sharpen throttle response, and unleash the deep, aggressive acoustic note of your variable-geometry turbocharger with premium 2010–2018 6.7L Cummins 4th Gen cold air intakes from Full Force Diesel. The 4th Generation Dodge Ram HD trucks are built to handle punishing workloads, but the factory intake system is heavily restricted by tight clearances, harsh acoustic baffling, and flat panel filters designed for basic noise reduction rather than maximum flow efficiency. Pushing your inline-six engine beyond factory performance constraints requires a steady, high-velocity stream of cold, dense oxygen. Upgrading to a specialized aftermarket induction system is the ultimate baseline modification to optimize combustion and improve efficiency across your entire power band.

Maximizing Air Density: Why Cold Air Beats Factory Inductions

A high-performance diesel engine acts like a massive air pump. Hot, restricted air starves the combustion chamber, resulting in sluggish off-the-line turbo lag and high EGTs when pulling heavy fifth-wheel trailers up steep grades.

• Engineered Heat Shielding: Premium aftermarket intake kits feature fully enclosed or heavily shielded airboxes that isolate the filter media from radiant under-hood engine heat. By drawing dense, ambient outside air from the fender well and front grille, these systems supply cooler oxygen to the compressor wheel.

• High-Flow Intake Tubes: Replacing the corrugated factory plastic intake duct with a smooth, oversized, mandrel-bent intake tube eliminates internal air turbulence. This streamlined pathway maximizes the volume of air flowing into the turbocharger, which reduces spool-up times and provides crisp, immediate throttle response.

Choosing the Right Filtration Media: Oiled vs. Dry Filters

When upgrading your induction system, matching your air filter media to your typical driving environment ensures maximum performance without sacrificing vital engine protection:

• Oiled Cotton Performance Filters: Ideal for highway driving, towing, and street performance applications. Oiled filters utilize multiple layers of progressive cotton gauze treated with specialized tack oil. This design achieves exceptional airflow characteristics (CFM ratings) while using the oil to trap fine particulates, and they can be washed, re-oiled, and reused for the life of the vehicle.

• Dry Synthetic Filtration Media: The premier choice for trucks frequently operating in heavy agricultural dust, oilfield job sites, or desert off-road conditions. Dry filters utilize advanced synthetic microfiber sheets that capture ultra-fine dust particles without needing oil. They are exceptionally low-maintenance and easily cleaned with compressed air or a vacuum, eliminating any risk of oil transferring onto sensitive downstream intake sensors.
