aFe 54-81022-1 Pro 5R Stage 2 Si Magnum FORCE Intake System

The simple yet elegant design of the 1-piece sealed housing makes installation a snap and features our patent-pending filter-to-housing interface. The heat-soak-resistant material ensures the coolest air intake charge available. A diamond tread plate pattern is molded directly into the top of the air-box to give your truck next-level personalization. A urethane plug is also included if you want to block off the auxiliary air inlet.

This system uses a CAD-designed, dyno-tuned, rotomolded intake tube to achieve maximum power gains while maintaining a perfect fit. With a MAF-to-Temp (Mass Air Flow to temperature) sensor adaptor, this intake system will work on all vehicles in the included application range equipped with either a MAF sensor or a temp sensor.

This Magnum FORCE intake system was designed around the largest filter possible to allow maximum performance and filtration. This filter has a massive 6.75″ x 4.75” elliptical flange and is 9″ tall with an inverted top. Its Pro 5R performance air filter media features 5 layers of progressively finer mesh cotton-gauze media, providing maximum airflow and performance.

Premium stainless-steel worm drive clamps are used for durability and provide the best corrosion resistance possible.
