Fits 2015 Subaru WRX STI Base, Launch Edition, and Limited models. This kit provides a complete intake solution by combining the COBB SF Intake with a custom-engineered air box designed to isolate the filter from power-robbing engine heat.

The COBB SF system utilizes a custom-coned filter and a CFD-designed velocity stack to maximize airflow into the turbocharger. The included air box is finished in a distinct blue and helps maintain lower intake air temperatures (IATs) by drawing in cooler ambient air from outside the engine bay. Constructed from high-quality composite materials, the intake tube reduces heat soak compared to traditional aluminum pipes, ensuring more consistent performance during spirited driving.

  • Direct-fit for the 2015 Subaru WRX STI platform
  • Includes SF Air Box with blue finish for superior heat shielding
  • High-flow, washable pleated cotton gauze filter media
  • CFD-optimized velocity stack for improved air velocity and turbulence reduction
  • Composite intake tubing minimizes heat transfer to the intake charge
  • Manufacturer Part Number: 715315-BL
