CSF Radiators BMW E46 M3 Race Triple Pass Radiator 7058 - R44 Performance

CSF Race Triple Pass Radiator for the BMW E46 M3 reduces the effects of heat soak and keeps your M3 running cool through prolonged periods of fast driving. Improve reliability for the road and track.

CSF Radiators produce the worlds finest all-aluminium engine water radiators, engine oil coolers, power steering coolers, gearbox oil coolers and intercoolers cores.

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 maximise 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 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 tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube with it the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow.”
- High Efficiency Multi Louvered Fin – CSF uses ultra efficient multi louvred fins that are carefully and precisely aligned to maximise 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.
