This 2011+ Subaru STI K&N Typhoon Air Intake System replaces the restrictive factory air filter and intake housing resulting in additional power and torque. The K&N Typhoon intake is a free-flowing induction system that features a mandrel-bent aluminum induction tube and a high-flow conical air filter designed to provide an increased surface area that allows even more airflow at lower restriction than a standard K&N OEM replacement filter, which is limited to the size of the factory air box. All K&N intakes come with a million mile limited warranty and are guaranteed to increase horsepower.
