The aFe Magnum FORCE Stage-2Si CIA system pairs dual 360-degree Pro DRY S radial filters with a vacuum-formed removable cover and a smooth XLPE housing that uses OE air inlets to deliver the coolest intake charge available. A dyno-tuned intake tube and factory mounting points simplify installation while producing measurable airflow gains. Designed for Porsche 911 (991) Carrera S and related 2012–2016 3.4/3.8L engines, it reports up to +15 HP and +13 lb-ft TQ in testing; note fitment considerations related to a 2020 Porsche engine-compartment heat-shield recall.
