Coolant temps can climb high enough on track to trigger limp mode, and OEM plastic radiators degrade over time with clogged tubes, damaged fins and a growing risk of cracked tanks or gasket failure.\u003c\/p\u003e\n\u003cp\u003eCSF's radiator uses its exclusive B-Tube technology and \"Track-Spec\" 5mm fins for a 20–25% gain in heat transfer efficiency, with 100% TIG-welded aluminum tanks instead of crimped plastic. It works with factory or aftermarket heat exchangers and is a true drop-in fit.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2-row 42mm ultra-high-performance core (OEM: 1-row 34mm)\u003c\/li\u003e\n\u003cli\u003eCooling tubes with CSF's exclusive B-Tube technology (approx. 15% more heat transfer than regular oval welded tubes)\u003c\/li\u003e\n\u003cli\u003e\"Track-Spec\" 5mm tall ultra-efficient multi-louvered fins (OEM: 4.5mm)\u003c\/li\u003e\n\u003cli\u003e20–25% increase in heat transfer efficiency\u003c\/li\u003e\n\u003cli\u003e67 cooling tubes, 68 cooling fin rows\u003c\/li\u003e\n\u003cli\u003eAluminum core and aluminum tanks (OEM: plastic tanks)\u003c\/li\u003e\n\u003cli\u003e100% all-aluminum TIG-welded construction (OEM: crimp-on gasket)\u003c\/li\u003e\n\u003cli\u003eCNC-machined mounting brackets and OEM-style inlet\/outlet\u003c\/li\u003e\n\u003cli\u003eHand-brushed satin finish\u003c\/li\u003e\n\u003cli\u003eTrue plug-and-play drop-in fit; no modifications required\u003c\/li\u003e\n\u003cli\u003eIndividually leak and pressure tested\u003c\/li\u003e\n\u003cli\u003eReplaces BMW OEM part number 17118482623\u003c\/li\u003e\n\u003cli\u003eCSF 2-year limited warranty, under normal use and service, to the original purchaser of the vehicle in which the product was originally installed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne (1) CSF #7089 high-performance all-aluminum radiator with CNC-machined mounting brackets\u003c\/li\u003e\n\u003cli\u003eComplete kit as supplied by CSF Radiators; CSF does not publish a full bill of materials for this part — see the instructions packed in the box.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e CSF Radiators specifies no additional hardware for this part — it is a drop-in replacement for BMW radiator 17118482623 using the OEM mounting points and fittings.\u003c\/li\u003e\n\u003cli\u003eInstaller-supplied: fresh BMW-spec coolant and distilled water to refill and bleed the system, plus a drain pan.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCSF does not publish a downloadable installation PDF for this radiator.
