| This coupler is like a little miracle.  It allows the installation of our mongloid 4" diameter FPAIP on any stock style turbocharger for the
 DSM.
 
 
Up to this point customers with 16g or FPBig28's or even old style smallinlet 20g turbos could not use the mongoloid 4" diameter FPAIP due to
 water pipe interference.  This unique product solves the problem by
 attacking it head on.  We make something from scratch if it doesnt
 exist.
 
 
As you can see from the pictures, the 4" FPAIP now clears the radiator hose, WG actuator and Jpipe.  This is due to the simple addition of an
 offset alignment of the reducer ends.
