CSF Radiators

CSF-8194

CSF Intercooler set for Audi C8 RS6

CSF’s strategic partnership with PWR brings F1 cooling design and technology to the high-performance aftermarket. These intercoolers help to keep charge temperatures consistently lower than the factory intercooler. This is because your factory intercooler was designed for standard power levels and expected type of use, as soon as you go outside of the factory power levels and expected type of use, your factory intercooler will begin to struggle. As well as this, as your intercooler goes through its life the core will deteriorate externally as well as fill with contaminates internally which results in a reduction in its performance.  

Over time the factory plastic end-tanks which are crimped onto the factory core can leak, losing precious boost pressure resulting in a significant lack of performance and risk to the engine. 

However, not all intercoolers are made equal. 

CSF Core design - Rolled Tube & Billet End Tanks

The CSF intercooler for the C8 RS6 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 our design. 

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