K&N Typhoon air intake for 2018–2019 Subaru WRX 2.0L Turbo replaces the restrictive factory airbox with a mandrel-bent aluminum tube and oversized K&N high-flow filter to reduce airflow restriction and improve throttle response. It includes a heat shield and is designed to accommodate the factory mass air sensor; the filter can remain serviceable for long intervals depending on conditions.
