An auxiliary radiator adds cooling capacity to the engine cooling system, lowering temperatures and delaying heat soak during aggressive driving so the engine is less likely to enter limp mode. It uses a 2-row 42mm core with CSF's B-Tube Technology and 5mm multi-louvered fins, in 100 percent TIG-welded aluminum with a satin black finish, an integrated mounting frame, a detachable rock guard, and OEM-style quick-connect inlet and outlet. It is a drop-in fit. Most cars use two auxiliary radiators, but the F87 M2 (N55) uses only one, mounted on the left. It does not fit the M2 Competition, which uses the S55 auxiliary radiators.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: high-performance auxiliary radiator\u003c\/li\u003e\n\u003cli\u003eCore: 2-row, 42mm, B-Tube Technology\u003c\/li\u003e\n\u003cli\u003eFins: 5mm, multi-louvered\u003c\/li\u003e\n\u003cli\u003eEngines: 3.0L turbo (N55\/B58), 2.0L turbo (430i)\u003c\/li\u003e\n\u003cli\u003eConstruction: 100 percent TIG-welded aluminum, integrated frame, detachable rock guard\u003c\/li\u003e\n\u003cli\u003eConnections: OEM-style quick-connect\u003c\/li\u003e\n\u003cli\u003eFinish: satin black\u003c\/li\u003e\n\u003cli\u003eQuantity: most cars use 2; F87 M2 uses 1 (left)\u003c\/li\u003e\n\u003cli\u003ePart number: 8355\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle Applications\u003c\/h3\u003e\u003cp\u003eFits the following (verify VIN\/BMW 17-11-8-625-447 for F3X\/F2X):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2016 BMW M2 (F87, N55)\u003c\/li\u003e\n\u003cli\u003e2017 BMW M2 (F87, N55)\u003c\/li\u003e\n\u003cli\u003e2018 BMW M2 (F87, N55)\u003c\/li\u003e\n\u003cli\u003e2016 BMW 340i (F30)\u003c\/li\u003e\n\u003cli\u003e2017 BMW 340i (F30)\u003c\/li\u003e\n\u003cli\u003e2018 BMW 340i (F30)\u003c\/li\u003e\n\u003cli\u003e2017 BMW 340i GT (F34)\u003c\/li\u003e\n\u003cli\u003e2018 BMW 340i GT (F34)\u003c\/li\u003e\n\u003cli\u003e2019 BMW 340i GT (F34)\u003c\/li\u003e\n\u003cli\u003e2017 BMW 440i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2018 BMW 440i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2019 BMW 440i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2020 BMW 440i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2017 BMW 430i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2018 BMW 430i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2019 BMW 430i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2020 BMW 430i (F32\/F33\/F36)\u003c\/li\u003e\n\u003cli\u003e2017 BMW M240i (F22\/F23)\u003c\/li\u003e\n\u003cli\u003e2018 BMW M240i (F22\/F23)\u003c\/li\u003e\n\u003cli\u003e2019 BMW M240i (F22\/F23)\u003c\/li\u003e\n\u003cli\u003e2020 BMW M240i (F22\/F23)\u003c\/li\u003e\n\u003cli\u003e2021 BMW M240i (F22\/F23)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the CSF 8355 fit?\u003c\/h5\u003e\u003cp\u003eThe BMW F87 M2 (N55), F30 340i, F34 340i GT, F32\/F33\/F36 440i and 430i, and F22\/F23 M240i.\u003c\/p\u003e\u003ch5\u003eWhat does an auxiliary radiator do?\u003c\/h5\u003e\u003cp\u003eIt adds cooling capacity, lowering temperatures and delaying heat soak so the engine is less likely to enter limp mode.\u003c\/p\u003e\u003ch5\u003eHow many are needed per car?\u003c\/h5\u003e\u003cp\u003eMost cars use two; the F87 M2 (N55) uses only one, mounted on the left.\u003c\/p\u003e\u003ch5\u003eDoes it fit the M2 Competition?\u003c\/h5\u003e\u003cp\u003eNo. The M2 Competition uses the S55 auxiliary radiators.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What vehicles does the CSF 8355 fit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The BMW F87 M2 (N55), F30 340i, F34 340i GT, F32\/F33\/F36 440i and 430i, and F22\/F23 M240i.\"}}, {\"@type\": \"Question\", \"name\": \"What does an auxiliary radiator do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It adds cooling capacity, lowering temperatures and delaying heat soak so the engine is less likely to enter limp mode.\"}}, {\"@type\": \"Question\", \"name\": \"How many are needed per car?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Most cars use two; the F87 M2 (N55) uses only one, mounted on the left.\"}}, {\"@type\": \"Question\", \"name\": \"Does it fit the M2 Competition?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. The M2 Competition uses the S55 auxiliary radiators.\"}}]}\u003c\/script\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":42401819033648,"sku":"CSF8355","price":389.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0586\/9548\/3440\/files\/44d290a36cf3be2e6e2e12cc4a8cea55L.jpg?v=1757646406","url":"https:\/\/berryperformancesales.com\/products\/csf-high-performance-auxiliary-radiator-bmw-f87-m2-f3x-f2x-8355","provider":"Berry Performance Sales","version":"1.0","type":"link"}
