The OEM B9 intercoolers deliver underwhelming performance, meaning this platform benefits greatly from an intercooler upgrade. Vehicles at stock boost levels up through Stage 1-2 as well as big turbo applications will all see a large improvement over the factory-equipped FMIC. 

This giant intercooler core is almost 2 times larger than stock and meets extensive quality control and pressure testing (up to 50psi). Cast aluminum end tanks attach to factory hoses seamlessly to ensure a boost-leak free fit that results in increased horsepower and torque.
