Description

The aFe TA-4306B-R Takeda Attack Stage-2 Cold Air Intake System is engineered to deliver major airflow improvements and impressive power gains for the 2015–2017 Subaru WRX STI. Featuring a CAD-designed red intake scoop, mandrel-bent wrinkle black intake piping, and a large 7-inch Pro 5R oiled air filter, this system dramatically increases airflow while maintaining excellent filtration.

Dyno-proven testing shows maximum gains of up to 21 horsepower and 24 lb-ft of torque, with a 56% increase in airflow over the stock intake system. The red cross-linked polyethylene scoop pulls in the coolest air possible, feeding it through a 2.75-inch mandrel-bent intake tube for fast, efficient airflow delivery to the turbocharger.

A high-quality ABS plastic heat shield helps block engine heat, reducing heat-soak and supporting consistent performance. The Pro 5R filter features five layers of progressively finer cotton gauze, offering excellent flow and filtration for both street and track use.

This system installs easily with no cutting or drilling required and includes all necessary clamps, couplers, and hardware. CARB EO D-550-23 applies to some applications, making portions of this system 50-state legal.
