The Injen SP1209P Short Ram Intake System in Polished finish is engineered to significantly improve airflow, turbo response, and overall performance for the 2015–2021 Subaru WRX with the FA20 2.0L Turbo engine. Featuring a large 3.00-inch mandrel-bent 6061-T6 aluminum tube, this intake system provides a smooth, unrestricted airflow path while maintaining proper air-fuel ratios using the factory ECU calibration.
Injen integrates its patented MegaRam (MR) Technology at the MAF sensor to ensure stable fuel trims, reducing the risk of check engine lights and eliminating the need for tuning. An application-specific heat shield and cover help protect the filter from engine bay heat and maintain consistent performance.
This system produces dyno-proven gains of up to 24 horsepower and 20 lb-ft of torque, along with an aggressive intake growl under throttle. With a clean, polished finish, it adds both performance and visual appeal to your engine bay. Manufactured in Pomona, California, this intake is backed by Injen’s Limited Lifetime Warranty.
