Injen SP1209WB Wrinkle Black Short Ram Intake for 2015–2021 Subaru WRX

The Injen SP1209WB Short Ram Intake System in Wrinkle Black provides improved airflow, increased throttle response, and noticeable power gains for the 2015–2021 Subaru WRX equipped with the 2.0L Turbo FA20 engine. This intake features a large 3.00-inch mandrel-bent 6061-T6 aluminum tube designed to work seamlessly with the stock ECU calibration, ensuring proper fuel trims and reliable performance with no tuning required.

Injen’s patented MegaRam (MR) Technology is integrated at the MAF point to help maintain accurate air-fuel ratios and prevent check engine lights. The included application-specific heat shield reduces heat soak and gives the intake a clean, OE-quality appearance. With dyno-proven gains of up to 24 horsepower and 20 lb-ft of torque, this system transforms the WRX’s responsiveness and induction sound.

Engineered, tested, and manufactured in Pomona, California, the SP1209WB delivers consistent, safe power while maintaining the reliability Subaru owners expect. Backed by Injen’s Limited Lifetime Warranty, this upgrade is a smart and stylish choice for WRX enthusiasts.
