*GTR ones are cheap,
*its hard to get a good finish with paint,(and im lazy)
*gtr came with black, if the paint still on after some 15yrs it must be decent quality,
*there are mixed opinions about the heat absorbtion of black intercoolers, many a debate about wether they are good or bad.
*I know a GTR one is decent quality, if i buy a silver one i will skimp and by a dodgy hybrid knock off......lol
