CSF are world leaders in cooling technology, manufactured in the USA for all manner of OEMs and performance brands. You can find their products at home on the Nurburgring attached to the latest highly strung Porsche 911 turbo or perhaps closer to home, keeping the HyperMiatas temperatures in check at willow springs, lap after lap after lap.
Used and recommended by experts in the MX5 / Miata racing scene – 949 Racing & Goodwin Racing there comes no higher praise than having CSF manufacture radiators to their own race spec.
“B-Tube” technology – Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a shape of a “B”. These “B-tubes” are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminium material (better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded.
The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tube by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube within the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow.”
The tubes are made from aircraft grade special clad aluminium and are intricately formed on our high precision 6-stage tube forming mill. No other aftermarket radiator manufacturer uses this technology. This technology raises the bar and sets the standard for high-performance radiator cores.
This unit will fit all 98-05 MK2/2.5 / NB/NBFL Mx5s and will keep you cool on track for years and years. Supplied with a quality CSF radiator cap and mounting brackets.
