The ARM B9 S4/S5 Intake optimizes airflow for the EA839 to support the most power and best times on your B9 S4/S5.  To achieve this, the ARM B9 S4/S5 Intake starts with a large 6" inverted high-flow conical air filter which provides a total surface area of 144 cubic inches.  This massive filter transfers airflow to the turbo inlet via our oversized 4" intake tube which is made with 6-ply high temperature reinforced silicone, and designed to push the filter deeper into the cooler area of the engine bay. 

The ARM B9 S4/S5 Intake completely replaces the restrictive OEM airbox. The OEM B9 airbox was designed to restrict the generous turbo sounds your EA839 naturally makes in order to keep the non-enthusiast happy. The ARM B9 S4/S5 Intake was designed with the enthusiast in mind. We removed all sound suppression features and restrictions to allow you to hear all the turbo sounds coming from your 3.0T.



The ARM B9 S4/S5 Intake comes included with a wrinkle black coated aluminum heat shield designed to help keep the hotter air generated by the 3.0T separate from the cooler air flowing into the engine bay through the OEM air snorkel.  The ARM Heat Shield is secured to the OEM threaded post on the strut tower with an included nut.  The OEM air snorkel channels cool air from the front grille directly at the ARM B9 Intake air filter.  Our B9 intake tube reduces to the 72mm which allows you to connect to either the ARM B9 S4/S5 Turbo Inlet or the OEM turbo inlet. 



The ARM B9 S4/S5 Intake ensures that your turbo receives a steady supply of cool, dense air, so you can get the most out of your EA839.  Whether you're looking for more power, or a more aggressive intake sound on your B9 S4 or S5, the ARM B9 S4/S5 Intake delivers both!
