CSF Racing 2-Row 52mm Race Spec Aluminium Radiator - Mazda RX-7 FD 92-97
Couldn't load pickup availability
The #1 choice in high-performance cooling for the unique Mazda rotary engine. Precise fitment requires no modifications to install. Designed to perform on track, and drifting. A must-have for high horsepower rotaries with built engines and/or addition of a forced induction system (turbocharger or supercharger).
CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology.
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 aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded.
The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes " producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow."
High Efficiency multi-louvered fins
CSF uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.
DESIGN & ENGINEERING
CSF aims to lead the cooling system industry by introducing new technologies and manufacturing processes that allows us to be on the cutting edge of heat transfer innovation.
ADVANCED ENDTANK DESIGNS
CSF offers three all-aluminum end-tank designs to match any style and performance need.
FINISH
Each CSF high-quality radiator is completed with an industry-leading 1 hour, hand-polished "Show-Stopper™" Mirror Finish. Our hand polishing tools and techniques in our new polishing center located at the end of the production line ensure that every CSF cooling system looks just as good as it performs.

Really fast and high quality customer support, my order got to me faster than the quoted time too. No complaints

The team took a mostly broken car after some work done elsewhere, and have systematically made it reliable and fast for a fair price. The staff are invested in the work they do which also makes a big difference.
