INCREASING POWER STARTS WITH IMPROVING AIRFLOW. EVEN THOUGH THE 2015 Subaru WRX comes equipped with an efictive intake, Extreme Turbo Systems developed an intake for the FA20DIT engine to improve airflow even more. The ETS 2015 Subaru WRX Air Intake Kit uses a K&N filter to increase surface area and a custom billet 5-inch velocity stack to help accelerate air flow. The filter placement takes advantage of the already effective stock ram air duct. To maintain bolt-on simplicity, the intake system includes a stock size MAF housing that does not require tuning. The optional air box helps to isolate the intake from hot engine bay temperatures
and thus provide a cooler intake charge. MSRP starts at $290.00.
