CSF Core design - Rolled Tube & Billet End Tanks

The CSF intercooler for the C8 RS6 & RS7 is a larger, more efficient intercooler for significantly improved cooling power. 

PWRs rolled tube cores are optimised in PWRs in-house wind tunnel, through this process PWR select the optimum stack height and multi-louvred fin design for both the ambient and pressure sides for optimum balance between cooling power and pressure drop.

CSF Manufacturing, Testing & Finish

These intercoolers are manufactured PWRs North American factory, this means PWR has total control over our production, unlike other white-label brands. PWR’s intercoolers start life in their factory as an aluminium sheet or bar and from there they create their own rolled tubes, multi-louvred fins, CNC machine all of the fittings. The core is then CAB brazed in their state of the art clean room and the end-tanks and fittings TIG welded together by their master welders. 

All of PWR’s intercoolers are individually leak tested and go through a fitment inspection to ensure critical dimensions are per CSF's design. 

To finish the intercoolers are only available in a raw finish.
