N55 Full Bolt on kit
Create a custom FBO Kit for your N55. Customize your full bolt on kit exactly how you want it for your build. The FMIC is a required upgrade for the FBO kit.
5" FMIC
7" FMIC
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. Below is a datalog from our project 335xi equipped with upgraded turbos, supporting modifications, and our ARM 1K FMIC. During 3rd gear datalogs we were seeing only 5 degree increases in IAT's from the beginning of the run to the end, the starting IAT being 59 degrees Fahrenheit, and still an icy cool 64 degrees at the finish.
Upgrading the downpipe on your N55 increases power, improves turbo spool, and allows you to run stage 2+ tuning, all while making your 135i or 335i sound better. The ARM N55 Downpipe is compatible with OEM and aftermarket midpipes, designed for a direct fit with the 80mm V-Band flange that accommodates both standard and upgraded turbo setups. An N55 downpipe upgrade is the first hardware upgrade every N55 owner should invest in for more power!
