The COBB SF Intake System for the 2015–2021 Subaru WRX is a performance-focused short ram intake designed to improve airflow, throttle response, and turbo sound while maintaining excellent drivability and reliability.

Unlike traditional cold air intakes, the SF Intake features a compact design paired with an airbox enclosure to help manage intake air temperatures and reduce heat soak compared to open short ram setups. The high-flow intake tube and custom-designed air filter are engineered to optimize airflow while maintaining stable mass airflow sensor readings.

Engineered by COBB Tuning, the SF Intake is designed to work seamlessly with COBB Accessport calibrations, making it an ideal upgrade for stock vehicles or those running a Stage 1 setup. Expect quicker turbo response and a noticeable but controlled induction sound that enhances the driving experience without being overwhelming.

This intake is a proven solution for WRX owners looking for easy installation, reliable performance gains, and strong tuning compatibility.
