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 the 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\". CSF also 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.\u003c\/p\u003e\n\u003cp\u003eThe CSF E39 M5\/540i radiator is a true \"Drop-in fit\" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet\/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.\u003c\/p\u003e\n\u003ch3 class=\"center\"\u003e⚠ Fitment Notes\u003c\/h3\u003e\n\u003ch4\u003eBMW 540i (E39) before 09\/1998\u003c\/h4\u003e\n\u003cp\u003eThe CSF #7064 comes with OE BMW quick connect radiator hose connections.
