Product Description

The aFe 54-13016D Magnum FORCE Stage-2 Cold Air Intake System is a high-flow performance upgrade designed for 2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L Duramax diesel engine. This intake replaces the restrictive factory air system with a large 9" inverted top conical Pro DRY S dry synthetic filter and a dyno-tuned XLPE intake tube engineered for maximum airflow and power gains. The open-element polymer housing helps draw cooler air into the engine while producing an aggressive induction sound that enhances the driving experience.

Installation is straightforward with direct bolt-on fitment using factory mounting points - no cutting or modifications required - and all necessary clamps and hardware are included. The Pro DRY S filter media is washable and reusable, providing long service intervals without the need for oil. Dyno-proven results show up to +17 HP and +37 lb-ft of torque over stock setups. This system outflows the factory intake by about 36% for improved engine breathing. Note that it is not CARB exempt and therefore not legal for sale or use in California, New York, Colorado, Maine, and other states with similar emissions regulations.
