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.
