This is a world-exclusive radiator, made exclusively for 928 International, that fits all 928 models. The CSF 928 radiator features two oil coolers; an engine oil cooler (left side) and a transmission oil cooler (right side). It’s a drop-in fit for all 928 models (both manual and automatic transmissions) with no modifications necessary. Another key feature is its ultra-efficient core with CSF’s exclusive B-Tube technology and multi-louvered fins, to maximize surface area for heat dissipation. Not only is the CSF 928 radiator a better performing unit compared to the OEM radiator, it’s also a fraction of the cost!
