The ARM 7” FMIC measures 20 x 7 x 5.75 inches for a total of 805 cubic inches, almost DOUBLE the size of the OEM 135i intercooler and 180 cu in larger than our 5” FMIC. Combined with our Ultra-Dense fin packs, not only are you getting a substantially larger intercooler, but also one that utilizes its size efficiently for maximum cooling performance.
The ARM 7” FMIC is the first ever intercooler upgrade for the E82 135i that has been engineered with CAD designed CNC aluminum connectors for you to utilize either the OEM intercooler hoses or upgraded intercooler hoses. Opting to utilize the OEM connectors will make for a faster and fully reversible install. While upgrading your 135i to the massive ARM 3in. intercooler hoses, you will be giving your 135i maximum airflow by removing any restriction the OEM connections may have on the charged air.
When testing the 7" FMIC on a Stage 2+ N54 335i we found it made an average of 10whp/10wtq over our 5" FMIC upgrade and 35whp/38wtq over the OEM intercooler!
