aFe MagnumFORCE Stage-2Si CIA System w/ Pro 5R Filter 12-15 Porsche 911 Carrera S (991) 3.8/3.8L | 54-83037R

Dual 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. They provide your engine with the largest amount of high-flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and/or track use. Their inverted tops make for more filter surface area, resulting in longer service intervals. The smooth housing, constructed of cross-linked polyethylene (XLPE), is used to minimize the number of components and ensure the coolest air intake charge available. The housing utilizes the factory OE air inlets. A vacuum-formed removable cover seals the system, ensuring cool air delivery to the engine, but can also be removed for extra air flow if desired. This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat soak resistant and extremely durable. The computer designed system utilizes factory mounting locations, minimizing the use of unnecessary hardware and ensuring a perfect fit every time. Its innovative design makes for a hassle-free, direct bolt-on installation process that requires no cutting or drilling. In 2020, Porsche created a recall to add a heat shield in the engine compartment under the air box. The heat shield is to prevent foreign objects left in the engine compartment to make contact with hot exhaust system components and ignite. aFe POWER housing will currently not fit with the heat shield added after the recall. aFe POWER is working on making an update to the housing to allow fitment with this heat shield.
