aFe TA-4305B-1R Takeda Stage-2 Pro 5R Intake for 2015–2021 Subaru WRX

The aFe TA-4305B-1R Takeda Attack Stage-2 Cold Air Intake delivers massive airflow increases, sharper throttle response, and impressive horsepower gains for the 2015–2021 Subaru WRX. Engineered with a CAD-designed red intake scoop, high-quality ABS heat shield, and a dyno-tuned intake tube, this system dramatically outperforms the restrictive factory intake system.

With dyno-proven gains of up to 28 horsepower and 32 lb-ft of torque, plus a staggering 131% increase in flow over stock, this kit unleashes the full potential of the WRX FA20DIT engine. The included 5" tall Pro 5R filter features five layers of progressively finer, oiled cotton gauze media, providing maximum airflow and superior filtration—ideal for both street and spirited driving.

AFe’s red intake scoop captures the coldest outside air possible, feeding it into the heat-shielded filter for consistent performance even under boost. Installation is fully bolt-on with no cutting or drilling required, and all necessary couplers, clamps, and hardware are included.
