Product Information
The aFe Magnum FORCE Stage-2 Si cold air intake for the 997.2 Porsche 911 encloses two 6 in tall, 360 degree radial flow Pro 5R filters in a two-piece XLPE housing with a heat resistant cover that also shields the MAF harness from engine bay heat. A computer designed, dyno-tuned XLPE intake tube resists heat soak, and the five-layer oiled cotton gauze filters can be washed and reused. The system flows 520 CFM at 7 in H2O, 25% more than the factory intake, and dyno testing showed gains of up to +8 hp and +10 lb-ft. It bolts to the factory mounting points with no cutting, and on 3.8L S models the changeover valve is closed off with the supplied cap.
