CSF ALUMINUM RACING RADIATOR- E46 M3When you buy a radiator from Team CSF you will receive a component that has been engineered to the highest specifications. CSFs parts will fit exactly the same as with the original manufacturers parts. No need to move fittings, drill additional holes, or stretch hoses to get their radiators to fit properly. Drop it in, bolt it down, and hook it up! No unpleasant surprises guaranteed!

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." The tubes are made from aircraft grade special clad aluminum and are intricately formed on our high precision 6-stage tubeforming mill. No other aftermarket radiator manufacturer uses this technology. This technology raises the bar and sets the standard for high performance radiator cores.

Features:

• 2 row 42mm core (dual core) featuring CSF's exclusive B-tube technology
• Core features an ultra-efficient fin with 6.5mm fin height and multi-louvered design for maximum surface area contact
• Triple-pass flow structure allows the coolant to flow across the core of the radiator 3 times before exiting the radiator for lowest outlet temperatures possible
• CNC machined "quick-connect" inlet/outlet connections
• CNC machined brackets and fittings for superb fit and durability
• All-aluminum race style drain plug
• 1 hour "mirror finish" hand polish
• "Drop-in fit" requiring no modifications to install.
• Accepts all attaching OEM components including "quick-connect" hoses, AC condenser mounting brackets, and fan shroud

Fitment:

• BMW M3 E46 01-06
