aFe Takeda Momentum Pro 5R Cold Air Intake System for 2018-2021 Subaru WRX STI (H4-2.5L)

Fits 2018-2021 Subaru WRX STI (Base, Limited, S209, and Type RA) with the H4-2.5L engine.

The aFe Takeda Momentum Pro 5R Cold Air Intake System is engineered for maximum airflow and thermal insulation. Built around a heat-resistant, one-piece cross-linked polyethylene (XLPE) housing, this system eliminates the multiple-piece designs of inferior intakes to minimize heat soak and simplify installation. The housing features a built-in, clear sight window for easy filter inspection and integrates with the included Dynamic Air Scoop to pull cool, dense air from the front of the vehicle and the fender well.

At the heart of this system is the Pro 5R air filter, a 7-1/2 inch tall, 360-degree radial flow filter featuring five layers of progressively finer pre-oiled cotton gauze media. This high-flow design outflows the factory intake by 56%, providing a measured flow of 320 CFM at 7" H2O. The computer-designed, dyno-tuned intake tube ensures precise fitment and optimized velocity, resulting in gains of up to +19 horsepower and +21 lbs. x ft. of torque.
