An ARM F30 Intercooler upgrade is one of the best modifications you can make to your N20/N26 or N55 powered BMW. The F3X's significant weak-point is its stock intercooler. This becomes obvious when tuning your F30 to increase boost with a Stage 1 tune and even more so with a Stage 2+ tune. With a higher boost target the charged air coming out of the turbo is hotter, therefore increasing IAT's. To compensate for the higher IAT's the ECU (DME) reduces boost, timing, and overall power to protect the engine. The ARM F3X FMIC Kit keeps your IAT's low allowing you to maximize the power your N20/N26 or N55 is capable of making. The ARM F3X FMIC is the perfect cooling solution for any stock turbo or upgraded turbo N20/N26 or N55 setup. With an intercooler core size of 20x11x3" and an overall volume of 660cu in. the ARM F30 FMIC is 235cu.in. or 36% larger than the stock N55 intercooler which comes in at only 425cu in. In addition, the ARM F30 FMIC utilizes an ultra-dense 14 fins per inch
