Product Description

The aFe TA-4305B-1R Takeda Attack Stage-2 Pro 5R Cold Air Intake System is a high-performance intake upgrade crafted for **2015-2021 Subaru WRX models equipped with the FA20DIT 2.0L turbocharged engine**. Designed to replace the restrictive factory intake, this system features a large, pre-oiled **5" Pro 5R filter** that provides superior airflow and filtration through its five-layer cotton gauze media. A CAD-designed roto-molded **red intake scoop** captures the coolest available air, while the ABS heat shield prevents engine bay heat from affecting intake efficiency, helping improve combustion performance and throttle response.

Constructed for a **direct bolt-on fit with no cutting or drilling required**, the TA-4305B-1R system also includes a high-quality roto-molded intake tube and all necessary hardware for installation. In-house dyno testing has shown gains of up to approximately **28 HP and 32 lb-ft of torque** over the stock intake in optimized applications, making it a popular choice for Subaru WRX owners seeking noticeable performance improvements. Note that this intake does **not fit models with Steering Responsive Headlights** and is **not CARB exempt** - it cannot be sold or used in California or other CARB-regulated states.
