CSF's Porsche 991 Turbo intercoolers have been race-tested, logged, and fully validated by some of the world's best Porsche tuners. These intercoolers have been regarded as the "Go-To" option for the best performance and value available in the performance aftermarket. From first glance the increase in width from the OEM's 80mm core to the CSF's 115mm width is very apparent. Critical for vehicles running performance tunes with bolt-on modifications. Considered a mandatory upgrade for vehicles running upgraded turbo systems. The larger capacity CSF bar/plate core design can handle significantly more airflow + increased boost pressures compared to the OEM intercooler system. CSF's 100% TIG welded cast end tanks, paired with its high-efficiency bar/plate intercooler core. Compared to the OEM style tub/fin core, which is crimped onto the plastic end tanks. The weaker OEM design can crack under high boost or vibrations typical to race conditions. The design of CSF's end tanks allows for airflow to be distributed evenly throughout the entire intercooler compared to the OEM intercooler design which is much shallower. The OEM design makes it more difficult for airflow to reach the top/bottom tube sections at the ends of the intercooler. CSF's Porsche 991 Turbo intercoolers are finished with an aero-space grade, Nano-particle, heat dispersion coating that dissipates heat around 35% better than uncoated raw aluminum. The coating is applied in California, USA by an aerospace coating company who also supplies coatings for Boeing. This unique coating is a key feature to achieving world-record performance, exclusively available from CSF.
