Product Description

The aFe TA-4301P Takeda Attack Cold Air Intake System is a performance-oriented intake upgrade engineered specifically for **Subaru Impreza WRX and WRX STI models from 2008 through 2014** equipped with the 2.5L turbocharged H4 engine. Its Stage-2 design utilizes a high-flow Pro DRY S synthetic air filter positioned to draw cooler, denser air from outside the engine bay, significantly improving airflow over the restrictive factory intake system. This improved airflow contributes to enhanced combustion efficiency, better throttle response, and increased power potential.

Constructed with a clear-coat polished aluminum intake tube and a large 360° Pro DRY S oil-free synthetic filter, the system delivers substantial gains - with dyno-proven increases of up to approximately **+34 HP and +31 lb-ft of torque** in optimized configurations. Installation is simple and requires no cutting or drilling, as the intake mounts directly using factory mounting points. The included high-flow dry filter is washable and requires no oil, simplifying maintenance while delivering dependable filtration. Perfect for Subaru performance enthusiasts, the Takeda Attack intake enhances both performance and engine bay aesthetics while maintaining 50-state legal compliance on applicable vehicles.
