CSF, along with its strategic manufacturing partner PWR, was the first company to introduce a high performance intercooler kit (CSF #8211/8211R) for the 4.0L engines in the Urus / RS Q8 / Cayenne Turbo in May of 2022. They've been a huge success and quickly had SQ7/SQ8 owners asking for a kit for their SUVs. With many examples pushing over 800hp, the coolers have proven to be an invaluable upgrade.While the original kit designed for the Urus / RS Q8 / Cayenne Turbo was able to be installed on the SQ7/SQ8, there were some modifications necessary and not a true "drop-in fit". Unitronic in Canada really brought the demand for an application specific set of intercoolers to our attention as they have a large customer base of SQ7s and SQ8s. Their tuning suite ups the SUVs power as high as 765bhp & 764 lb-ft. Manufacturing of the USA-made CNC billet end tank intercoolers takes place at PWR North America in Indianapolis. This strategic partnership continues to flourish with this exciting new model for the SQ7/SQ8, allowing CSF to bring PWR's Formula 1 cooling technology to the performance aftermarket.The SQ7/SQ8 Intercoolers have been meticulously designed and engineered to fit exactly like the OEM units they replace. Utilizing all factory mounting points, the installation is straightforward with a "drop-in fit" design. No cutting or modifications are required, and there is no need for aftermarket shrouds or hoses. All mating OEM components can be reused and reinstalled. There are two available finishes for the intercoolers. A raw billet aluminum finish or Thermal Black Heat Dispersion Cerakote to further the cooling efficiency of these Intercoolers. The Thermal Black coating is able to dissipate heat about 15% faster than raw billet.CSF has integrated the charge pipe into the design of the top end tank with an aluminum welded pipe replacing the factory bolt-on plastic part which is sealed with an inner O-Ring. The OEM O-Rings may be a factory design flaw many owners have had to replace them on their stock systems. This failure causes boost leaks and triggers a check engine light which is quite surprising on such a new vehicle.The same intercooler cores used in this application are the same style used in other CSF air-to-air systems developed for the Urus/RS Q8/Cayenne Turbo, Audi RS6/RS7, and Porsche 992 Turbo/S, with incredible results. These cores eliminate heat soak and lower Intake Air Temperatures (IATs) much more efficiently than traditional Bar & Plate designs. This gives us maximum performance for extended periods of time under demanding driving conditions and in vehicles with increased power levels through modifications and tuning. The 4.0L twin-turbo V8 in the SQ7/SQ8 starts to experience debilitating heat soak and progressively increasing IATs with the OEM intercoolers. This results in the ECU pulling engine timing and drastically decreasing power output. The CSF by PWR Intercoolers solve this issue and allow vehicles to perform at optimal levels consistently and for prolonged periods of time.As with CSF's other products produced through our PWR partnership, the new SQ7/SQ8 Intercoolers feature 100% TIG-welded machined billet aluminum end tanks. Compared to the OEM crimped plastic composite end tanks this is a very significant upgrade. This feature is not only aesthetically pleasing, but is also stronger offering longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from bolt-on modifications, higher performance tunes, as well as upgraded turbochargers.What is truly remarkable about the CSF by PWR systems is their ability to recover and fight off heat-soak. The ability to maintain consistent power (and temperatures) run after run is more important than power gains in any motorsport setting. From our own testing on the RS6 coolers (which use similar core specs as the SQ7/SQ8 coolers), the biggest delta between CSF and OEM is that the performance from the OEM coolers deteriorates quickly after several dyno runs. Compare that to the CSF coolers and they stayed consistent from the first run right through to the fifth. This is especially beneficial for track cars, drag cars and even fast road cars. There's no power loss because of heat-soak.The CSF by PWR SQ7/SQ8 Twin Intercooler Set features Formula-1 grade cores which offer the greatest reduction in IATs and help eliminate heat soak. The Billet Aluminum construction offers the greatest strength and durability possible.
