COBB Tuning SF Air Intake System Subaru WRX (VA)

Cobb Tuning SF Air Intake System - Subaru WRX VA 15-21

COBB Tuning is one of the most respected names in Subaru performance, and the SF Intake System is their entry level intake upgrade designed to reduce pre-turbo restrictions and free up power without requiring major modifications. A well-engineered bolt-on upgrade for the Subaru WRX VA, this intake replaces the factory airbox with a purpose-built aluminium unit and a CFD-developed velocity stack MAF housing to keep airflow smooth and the MAF sensor reading accurately.

This listing covers the COBB SF Intake System for the 2015–2021 Subaru WRX (VA) equipped with the FA20 engine. One variant is available.

Note: Calibration is required. This intake is compatible with the stock tune and COBB Off The Shelf (OTS) maps denoted with "+SF" via Accessport. Consult the COBB maps section for a full list of compatible maps for your vehicle.
