In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eFeatures and Benefits\u003c\/h4\u003e\n\u003cul class=\"fab-list\"\u003e\n\u003cli\u003eCore Size: 524mm Length x 478mm Height x 69mm Wide\u003c\/li\u003e\n\u003cli\u003eReplaces OEM Part Number: 17118741830\u003c\/li\u003e\n\u003cli\u003e68mm 2-Row Core with CSF's B-Tube Technology (World's Largest 2-Row Core)\u003c\/li\u003e\n\u003cli\u003e6.5mm Multi-Louvered Fin Height\u003c\/li\u003e\n\u003cli\u003eTriple-Pass Flow Design\u003c\/li\u003e\n\u003cli\u003eIncluded Detachable Rock Guard\u003c\/li\u003e\n\u003cli\u003eOEM CNC Machined Mounting Location Pins and Brackets\u003c\/li\u003e\n\u003cli\u003eDirect Plug-and-Play Design, Including CNC Machined \"Quick Connect\" Inlet\/Outlet Water Fittings\u003c\/li\u003e\n\u003cli\u003eNo Modifications Needed to Install\u003c\/li\u003e\n\u003cli\u003e1-Hour \"Mirror Finish\" Hand Polish\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":47378164973707,"sku":null,"price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/5084\/8395\/files\/c7d26c6b12ee8b2d4bdc5257790e0fa0M.jpg?v=1781833942","url":"https:\/\/gbmotorsstore.com\/products\/csf-bmw-b58-b48-front-mount-triple-pass-heat-exchanger-w-rock-guard","provider":"GB Motors Store ","version":"1.0","type":"link"}
