Product Description

The aFe Power 51-11872-1 Magnum FORCE Stage-2 Cold Air Intake System is a high-flow performance upgrade designed specifically for 2011-2016 Ford Super Duty trucks equipped with the 6.7-liter Power Stroke turbo-diesel engine. This intake replaces the restrictive factory air system with a large open-element design that dramatically increases airflow - often up to around 45%-64% more than stock - for improved engine breathing and enhanced power potential. The oversized Pro DRY S dry synthetic media filter requires no oiling and provides excellent filtration with easy washing and re-use.

The 51-11872-1 features a dyno-tuned roto-molded intake tube and a unique 3-angle filter adapter to optimize airflow dynamics, helping deliver estimated gains of up to approximately +26 HP and +80 lb-ft of torque while adding a more aggressive induction sound and turbo whistle under acceleration. Its open-element housing reduces intake air temperatures and draws in more air compared to stock, all with a direct bolt-on installation that uses factory mounting points - no cutting or drilling required. Note: this intake is not CARB exempt and is not legal for sale or use in California or other CARB-equivalent emissions-controlled states.
