Ive got my 2001 996tt going to get some upgrade next week. Im going with k-24 turbos, maxspeed header/exhaust system, v-flow intake and a giac ecu flash. how important would it be to upgrade the intercoolers? ive been looking at the evo and blownsix intercoolers. Is thier any hp gain? Is it worth the extra cash to go with the upgrade? any input would be grateful---walt
