aFe Takeda Momentum Pro 5R Cold Air Intake System 56-70014R for 2018-2021 Subaru WRX STI 2.5L H4

Large Five Layer Performance Air Filter: Momentum's innovative filter-to-housing interface was built to feature the largest air filter possible. This 7-1/2 IN tall 360-degree radial flow air filter features a 3-1/2" flange and our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases. This media is perfect for street and/or track use. Its inverted top makes for more filter surface area, resulting in longer service intervals. Unique One-Piece Housing: The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE) polymer, features our patent-pending filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system. The system captures cool air with an included Dynamic Air Scoop at the front of the vehicle and an additional air inlet in the vehicle's fender well. Dyno-Tuned Intake Tube: 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. Hassle-Free Installation: Stainless-steel clamps and silicone couplings are included for strength and durability. Momentum intakes are designed with fewer parts for a fast and easy installation. Takeda Momentum Cold Air Intake System w/ Pro 5R Filter Subaru WRX STI 18-21 H4-2.5L (t)

Brief Description: The aFe Takeda Momentum Pro 5R Cold Air Intake System is engineered to improve airflow, throttle response, and engine performance in the 2018-2021 Subaru WRX STI with the 2.5L turbocharged H4 engine. Part number 56-70014R combines a high-flow five-layer cotton gauze filter, sealed XLPE housing, and dyno-tuned intake tube for a direct-fit upgrade over the factory intake system.

The large, pre-oiled Pro 5R filter uses five progressively finer layers of cotton gauze media to support high airflow for street or track applications. Its radial-flow design and inverted top increase usable filter surface area, helping extend service intervals. The sealed housing draws cooler air through the included Dynamic Air Scoop and an additional fender-well inlet, while the clear sight window allows filter inspection without removing the intake assembly.

The computer-designed intake tube is manufactured from heat-resistant cross-linked polyethylene for durability and reduced heat soak. Stainless-steel clamps and silicone couplings provide secure connections, and the system uses fewer components to simplify installation. In testing, the intake flowed 320 CFM at 7 inches of water, outflowed the factory intake by 56%, and produced gains of up to 19 horsepower and 21 lb.-ft. of torque. This product is not CARB approved and may not be legal for use on pollution-controlled vehicles in some areas.

Fitment: Fits 2018, 2019, 2020, and 2021 Subaru WRX STI models equipped with the 2.5L turbocharged H4 engine.
