Product Details
The 6061-T6 aluminum intake tube in this Injen SP Series cold air intake is mandrel-bent for a smooth, uninterrupted path for air entering your 2018-2021 Subaru WRX STI's turbo. This design helps eliminate restrictions found in the factory airbox, allowing your H4 2.5L turbo engine to breathe more freely and reach its full power potential.
This intake system is designed as a direct replacement for your stock airbox, making installation straightforward. It features Injen's SuperNano-Web dry air filter, which offers a large surface area for increased airflow and effective filtration without needing oil. You can expect an aggressive and throaty engine tone under acceleration, and dyno tests show gains of up to 26 horsepower and 24 lb-ft of torque without requiring an ECU tune. Injen also backs this intake with a limited lifetime warranty.
