Product Description

CSF’s high-performance all-aluminium water radiators help to keep coolant temperatures consistently lower than the factory radiator. This is because your factory radiator 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 radiator will begin to struggle. As well as this, as your radiator goes through its life, the core will deteriorate externally as well as fill with contaminates internally to reduce its cooling power. 

However, not all radiators are created equal. 

CSF Core design

The CSF radiator for 2008+ Subaru WRX and STI is a larger, more efficient radiator for significantly improved cooling power. CSF’s cores are unique in that it uses our B-tube design for the radiator tubes. 

The B-Tube core is comparatively stronger than the O-Tube which allows the tube to be made using less material, improving heat transfer and being much lighter than an O-Tube radiator of the identical sizing. This, combined with the dual laminar flow and improved surface area inside the core allow for an efficiency improvement of around 10-20% vs. an O-Tube core radiator of the same size. Whilst more expensive to manufacture, for performance use, it is the perfect radiator tube design! Alongside this our high-efficiency multi-louvred fins are optimised for each application. 

This core for this radiator utilises a single-row high-performance 31mm thick.

CSF Manufacturing, Testing & Finish

All of our radiators are manufactured in our own factories, which means we have total control over our production, unlike other white-label brands. Our radiators start life in our factory as an aluminium sheet, and from there we create our own B-tubes, multi-louvred fins and end-tanks as well as CNC machine all of our fittings. The core is then CAB brazed and the end tanks and fittings TIG welded together by our master welders. 

All of our radiators are individually leak tested and go through a 30-point fitment inspection to ensure critical dimensions are per our design. 

To finish our radiators our signature 1-hour ‘show-stopper’ finish is applied, however, this has currently been suspended during the pandemic in favour of our high-lustre satin finish.
