The Injen SP1209WR Short Ram Intake System in Wrinkle Red is engineered to provide improved airflow, sharper throttle response, and noticeable power gains for the 2015–2021 Subaru WRX 2.0L Turbo. Featuring a large 3.00-inch mandrel-bent 6061-T6 aluminum intake tube, this system delivers a smooth, unrestricted airflow path designed to work safely with the factory ECU calibration.
This intake includes Injen’s patented MegaRam (MR) Technology at the MAF sensor location, helping maintain accurate fuel trims without requiring tuning or causing check engine lights. A fully integrated, application-specific heat shield helps protect the filter from engine bay heat, ensuring cooler airflow and consistent performance.
With dyno-proven gains of up to 24 horsepower and 20 lb-ft of torque, an aggressive induction tone under acceleration, and a clean, OE-like fitment, the SP1209WR is one of the best bang-for-the-buck upgrades for the FA20-powered WRX. Manufactured in Pomona, California and backed by Injen’s Limited Lifetime Warranty, this intake is built for performance and reliability.
