Subaru WRX STI Performance Air Intake - COBB Air Box (2019–2021). A quality intake and enclosed airbox designed to improve airflow and turbo response while keeping a factory-like fit for your STI.

This COBB setup replaces the restrictive stock tract with a high-flow filter and an airbox that helps shield the intake from engine heat. It draws fresh air from the OEM snorkel, maintains reliable MAF readings, and mounts to factory points with included hardware for a straightforward bolt-on. Service is simple, and the enclosed design supports consistent performance in a variety of driving conditions.

Features

• Direct fit for 2019–2021 Subaru WRX STI
