The FMIC kit comes with a large 23.5x10x4 inch core and all piping needed for installation. The major downfall to the FMIC is it requires the use of a smaller battery and is flanged for a universal HKS BOV not the stock BOV.
**Stock recirculation cannot be used; Size of battery needs to be changed (B19L); Racing Suction Reloaded (70020-BF010) is required separately
