So when it comes to keeping your engine cool and your E46 M3 running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. The Triple-Pass Flow Structure allows the coolant to flow across the core of the radiator three times before exiting for lowest outlet temperatures possible. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape \"O\" type radiator tube, CSF uses a specially engineered tube in the 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 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\u003ch4\u003eFeatures and Benefits\u003c\/h4\u003e\n\u003cul class=\"fab-list\"\u003e\n\u003cli\u003e2 Row 42mm Core (Dual Core) Featuring CSF's Exclusive B-Tube Technology\u003c\/li\u003e\n\u003cli\u003eCore Features an Ultra-Efficient Fin with 6.5mm Fin Height and Multi-Louvered Design for Maximum Surface Area Contact\u003c\/li\u003e\n\u003cli\u003eTriple-Pass Flow Structure Allows the Coolant to Flow Across the Core of the Radiator 3 Times Before Exiting for Lowest Outlet Temperatures Possible\u003c\/li\u003e\n\u003cli\u003eCNC Machined \"Quick Connect\" Inlet\/Outlet Connections\u003c\/li\u003e\n\u003cli\u003eCNC Machined Brackets and Fittings for Superb Fit and Durability\u003c\/li\u003e\n\u003cli\u003eAll-Aluminum Race Style Drain Plug\u003c\/li\u003e\n\u003cli\u003eSmooth Satin Finish\u003c\/li\u003e\n\u003cli\u003e\"Drop-in Fit\" Requiring No Modifications to Install - Accepts All Attaching OEM Components Including \"Quick Connect\" Hoses, AC Condenser, Mounting Brackets and Fan Shroud\u003c\/li\u003e\n\u003cli\u003eReplaces OEM Part Number: 17102228941\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":44505042649224,"sku":"csf7058","price":599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/8170\/0232\/files\/04167b24ce2724bf17802caeda727605M.jpg?v=1763999990"},{"product_id":"bmw-e46-m3-race-spec-dual-pass-oil-cooler","title":"BMW E46 M3 Race-Spec Dual-Pass Oil Cooler","description":"\u003cp class=\"prod-overview\"\u003eThe CSF x Rogue oil cooler uses a Bar \u0026amp; Plate construction (vs. tube and fin) in a top\/bottom configuration. The Bar \u0026amp; Plate design makes the cooler much more robust and able to take abuse from debris hitting it at high speeds on the road or track. The cooler uses extruded end tanks which means it is a much stronger design than simple bent aluminum sheet construction found on the oem unit. The cooler is a bolt on design for the factory radiator or the CSF High-Performance Radiators (E46 M3 - CSF #7058 \/ E39 M5 - #7064) and uses the factory oil cooler lines. \u003c\/p\u003e\n\u003ch4\u003eFeatures and Benefits\u003c\/h4\u003e\n\u003cul class=\"fab-list\"\u003e\n\u003cli\u003eDesigned, Developed, and Track Proven in Collaboration with BMW M3 Tuning Specialist and Parts Manufacturer, Rogue Engineering\u003c\/li\u003e\n\u003cli\u003eReplaces OEM Unit Single-Pass Design and Plastic Shroud with a Unique Top\/Bottom Dual-Pass Design for Maximum Surface Area and Flow\u003c\/li\u003e\n\u003cli\u003e\"Drop-in Fit\" Requiring No Modifications to Install - Accepts Factory Oil-Line Connections\u003c\/li\u003e\n\u003cli\u003eFully TIG-Welded Extruded-Endtank Design vs. OEM Mechanically Jointed and Tack-Welded Design for Superior Reliability \u0026amp; Durability\u003c\/li\u003e\n\u003cli\u003eFits Precisely with the Contour of the OEM Bumper - No Issues with Aftermarket Splitter Attachment\u003c\/li\u003e\n\u003cli\u003eTurbulated Heavy-Duty Bar\/Plate Design for the Most Reliable \u0026amp; Durable Oil Cooler Available for the Platform\u003c\/li\u003e\n\u003cli\u003e8 Rows of Maximum Cooling with a High Density Multi-Louvered Fin Pitch Design\u003c\/li\u003e\n\u003cli\u003eDesigned to Work with OEM Radiator Brackets or CSF's All-Aluminum Triple-Pass Radiator (CSF #7058)\u003c\/li\u003e\n\u003cli\u003eMotorsport Silver Finish\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":44505062736008,"sku":"csf8032","price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/8170\/0232\/files\/e9e4c8cab4ad3944b845efce67cb18b3M.jpg?v=1764000494"}],"url":"https:\/\/ep3motorsports.com\/collections\/e46-cooling.oembed","provider":"EP3 Motorsports","version":"1.0","type":"link"}
