aFe Takeda Attack Stage-2 Cold Air Intake - Subaru WRX STI (VA) - 2.5L Turbo
The aFe Takeda Attack Stage-2 Cold Air Intake replaces the factory airbox on the 2015-2017 Subaru WRX STI (VA) with the 2.5L turbo. A red XLPE scoop pulls in cool air, an ABS plastic heat shield keeps engine heat off the 7in (178mm) tall conical filter, and a one-piece 2.75in (70mm) mandrel-bent tube in wrinkle black powder coat feeds the turbo.
Fitment Note
Suits the 2015-2017 WRX STI (VA) only. For the 2018-2021 STI see the Takeda Momentum intake.
