Product Description

The aFe 51-30392 Magnum FORCE Stage-2 Cold Air Intake System is engineered to significantly improve airflow and performance on Ford 6.0L Powerstroke diesel engines used in Super Duty trucks and Excursions from 2003-2007. By replacing the restrictive factory airbox and intake ducting with a high-flow dry synthetic Pro DRY S filter and smooth molded plastic tube, this intake delivers up to ~31% more airflow, resulting in measurable gains in horsepower and torque without major modifications.

Installation is straightforward with included hardware, and the one-piece powder-coated heat shield helps isolate the intake from engine bay heat for denser air delivery. The Pro DRY S filter's oil-free synthetic media makes maintenance easier, and its reusable design offers long service life. While tuning is not required for basic operation, pairing this intake with an optimized engine tune can further enhance performance. Always check local emissions requirements - some states may restrict aftermarket intake systems despite CARB exemption status.
