CONSTRUCTION

The foundation of the ARM 1K FMIC is it’s massive core with a volume of 1,155cu in. Measuring in at 20″x11″x7.5″ it is 270% bigger than the stock intercooler and one of the largest FMIC’s available for the E-Series BMW.

Size does matter, but it’s not the whole story. Which is why the ARM 1K FMIC utilizes an ultra-dense fin pack of 20 fins per inch to maximize the volume of it’s huge core.

Combine the over-sized core with the ultra-dense fin packs of the 1K FMIC and you have one of the best performing intercoolers available for the E-Series BMW.

The ARM 1K FMIC end-tanks are designed with smooth transitions and geometry to improve airflow and maximize power. The end-tanks feature 3″ inlet and outlet ports with fluid transitions from the turbos and to the charge pipe to minimize turbulence.

The ARM 1K FMIC features a cast fin integrated into the inlet port to distribute the charge air more uniformly over the turbo-side of the intercooler core.
