Injen SP1207P Polished Short Ram Cold Air Intake for 2015–2021 Subaru WRX

The Injen SP1207P Short Ram Cold Air Intake System in Polished finish is designed to unlock additional power, improve throttle response, and enhance airflow for the 2015–2021 Subaru WRX 2.0L Turbo. As part of Injen’s flagship SP Series, this intake utilizes patented MegaRam (MR) Technology and Air Fusion Technology to provide safe, repeatable power gains while maintaining factory air-fuel ratios — with no tuning required.

Crafted from 6061-T6 mandrel-bent aluminum, the SP1207P offers a smooth airflow path to the turbocharger. A custom, application-specific heat shield reduces heat soak, ensuring colder and more consistent incoming air. The fully serviceable SuperNano-Web dry filter increases surface area and filtration efficiency for maximum performance.

This intake produces dyno-proven gains of up to 17 horsepower and 17 lb-ft of torque, along with a deep, aggressive intake tone under throttle. Featuring a polished finish for a clean and vibrant engine bay appearance, the SP1207P is manufactured in Pomona, California and backed by Injen’s Limited Lifetime Warranty.
