Description

The aFe TA-4306B-D Takeda Attack Stage-2 Cold Air Intake System with Pro DRY S filter delivers impressive power gains, improved throttle response, and cooler airflow for the 2015–2017 Subaru WRX STI. Designed with a CAD-modeled red cold-air scoop, ABS heat shield, and a mandrel-bent intake tube, this system outperforms the factory intake while maintaining OEM-like fitment.

Dyno testing shows increases of up to 21 horsepower and 24 lb-ft of torque, thanks to aFe’s large 7-inch oil-free Pro DRY S filter and optimized airflow path. The scoop channels fresh outside air directly into the intake, while the ABS heat shield protects the filter from engine heat to reduce heat-soak and sustain performance.

The Pro DRY S filter features three layers of progressively finer synthetic media, offering excellent airflow and filtration without the need for oiling. This makes it ideal for daily driving and light off-road use while keeping maintenance simple.

With included clamps, couplers, and hardware, installation is straightforward with no cutting or drilling required. CARB EO D-550-23 applies to some applications, allowing 50-state legal use where specified.
