aFe Magnum FORCE Stage-2Si intakes, Porsche 997/991

Dual 6” tall 360-degree radial flow air filters feature our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Their progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Their inverted tops make for more filter surface area, resulting in longer service intervals. The enclosed housing features two pieces constructed of cross-linked polyethylene (XLPE), ensuring the coolest air intake charge available. The housing and cover are designed to protect the MAF harness from the extreme temperatures of the engine bay. 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. This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and premium aFe POWER branded hardware is included.
