item: CSF Racing 2-Row 42mm Race Spec Aluminium Radiator for Mazda MX-5 NB 98-05

The go-to option and private label partner for the biggest names in Miata performance – including Good-win Racing, 949 Racing (Super Miata), Moss Motorsports, Jackson Racing, and Flyin’ Miata.

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-Stopperâ„¢" 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.
