What is a FMIC?

Front-mount intercooler.  

Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the entire supercharger system. Common spatial designs are front mounted intercoolers (FMIC), top mounted intercoolers (TMIC) and hybrid mount intercoolers (HMIC). Each type can be cooled with an air-to-air system, air-to-liquid system, or a combination of both. Typically DSM use Air to Air.

It is important to note that FMICS: The larger the tank, the longer the piping, the more lag.  

Meth/Water injection will not cool intake temps as well without an FMIC, but you CAN run without FMIC. Some have had limited success.

Also, an FMIC will add a little intimidation factor to your [DSM].
