Air intake systems are designed to improve airflow to the engine by reducing restriction and drawing in cooler, denser air. Increased airflow can support improved throttle response, engine sound, and overall performance compared to restrictive factory intake systems.
Air intake upgrades are a popular modification for Subaru WRX and STI owners looking for a straightforward performance improvement. Depending on the design, intake systems can prioritize maximum airflow, enhanced induction sound, or balanced drivability for daily use.
Air Intake System Options
This category includes complete intake systems as well as individual components designed to support a wide range of build goals. Whether you’re upgrading airflow, replacing worn factory parts, or fine-tuning your intake setup, selecting the right intake components depends on vehicle configuration and intended use.
