Product Description

The aFe 51-81711 Magnum FORCE Stage-2 Si Cold Air Intake System with Pro DRY S filter is a high-performance direct-fit upgrade designed for select Volkswagen and Audi models equipped with the 2.0L TDI engine. This sealed intake replaces the restrictive stock airbox with a CAD-designed roto-molded tube and sealed housing that draws in cooler ambient air, enhancing engine breathing and throttle response without requiring ECU tuning. The included Pro DRY S synthetic air filter is oil-free, washable, and reusable for easy maintenance and long life.

With improvements in airflow of up to approximately 56 % over the factory unit and dyno-proven gains of up to around +10 HP and +23 lb-ft of torque, this Magnum FORCE intake offers a notable performance uplift for diesel-powered VW and Audi vehicles. Bolt-on installation uses factory mounting points and hardware with no cutting or drilling required, and a sleek sealed housing with an aluminum cover helps minimize heat soak for consistent performance. Note that this intake is not currently CARB exempt and may not be legal for sale or use in California or other states with strict emissions requirements - always verify local regulations before purchase.
