CSF Performance Radiator BMW 2008 - 2010 135I L6 3.0 Automatic Trans 7046
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.
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 (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 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."
CSF uses special "B-Tube" technology in place of traditional "O" type tubes for higher efficiency and added strength.
With "B-tubes" you are able to get "dual liquid laminar flow."
Each CSF radiator is completed with an industry leading 1 hour, hand polished Sho-Stopper mirror finish.
