ARM FMIC for Audi B9 S4/S5

Overview

The ARM Audi B9 3.0T S4 / S5 Competition FMIC is engineered to keep IAT's low during back-to-back pulls. By dramatically increasing intercooler core volume to a staggering 1,485cu/in and improving airflow efficiency with internal air channels, this system is designed to reduce heat soak, stabilize intake air temperatures, and maintain consistent performance pull after pull. Whether you have stock turbo or upgraded turbo, the ARM B9 FMIC will keep your EA839 running cool!

The OEM intercooler on the Audi B9 3.0T platform is sufficient for light daily driving, but it quickly becomes a limitation under sustained boost, aggressive driving, or tuning. As intake air temperatures rise, timing is reduced and power output becomes inconsistent, making your second or third runs suffer from reduced power.
