Description
CSF’s Twin Intercooler Set replaces both factory intercoolers on the 991 911 GT2 RS and its 3.8L twin-turbo flat six. Each cooler uses a heavy-duty bar-and-plate core, two rows with 3mm rolled tubes and turbulated inner fins, 87mm thick, between all-aluminum cast end tanks. The set is pressure tested to 120 psi and finished in CSF’s thermal rejection powder coating. It drops into the factory location with no modification and no trimming of the OEM carbon fiber ducts.
