Part Number 54-83037R

Advanced FLOW Engineering (aFe Power) designs and manufactures performance air, exhaust and power-management systems for trucks, SUVs and sport compacts, with a particular strength in diesel truck performance. Founded in 1999 and still headquartered in Corona, California, aFe builds in-house across two facilities totalling 164,000 square feet — filters, intakes, exhaust, headers, intercoolers and torque converters are made on site, with CNC machining, mandrel tube bending and dyno testing under the same roof. The catalogue spans cold air intakes, direct-fit and racing air filters, cat-back and axle-back exhaust, intercoolers, turbochargers, electronic programmers, diesel fuel systems and throttle body spacers, across more than 2,500 applications. Recognisable product families include Pro 5R, Pro Dry S and Pro Guard 7 filter media, Takeda for sport compact intakes and exhaust, BladeRunner intercoolers and manifolds, Scorcher programmers, Aries powersports filtration, and aFe Control for suspension and chassis.

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.
