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. 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. - Sold as a pair (Left & Right Intercoolers) - Eliminates Heat Soak and Lower Intake Air Temperatures (IAT) for Maximum Performance in High-Performance and Race Conditions - Formula-1 Performance Grade Cores by PWR (2-Row Cores features Rolled Tubes w/ Inner Fins) - CNC Machined Billet End Tanks - 100% TIG Welded vs OEM Crimped Plastic End Tanks for Maximum Strength & Durability - Made in the USA at PWR North America - Integrated 1/8th NPT Port with plug on lower outlet tank for Water-Methanol Injection - OEM Style Inlet/Outlet Connections for Precise Fitment With All OEM Components - True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications - Performance Testing by Unitronic - 1-Piece Welded Charge Pipe vs OEM Bolt-On Pipe w/ O-Ring (known failure point)
