The heat exchanger uses a 2-row 42mm core with CSF's B-Tube Technology, 6.5mm multi-louvered fins, all-aluminum TIG-welded tanks, and an integrated metal rock guard. The transmission cooler is a dual-core design with 201 percent more core volume, using a 1-row super-high-pressure 16mm 9-channel microtube with 15 tubes and 16 rows. It has a hand-brushed satin finish, OEM-style quick-connect connections, and pre-installed foam sealing strips, and it is a plug-and-play drop-in fit. It also fits the G01 X3 M40i and G02 X4 M40i (B58) built after 08\/2019, which may need minor line adjustments.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: integrated cooling module (heat exchanger + transmission oil cooler)\u003c\/li\u003e\n\u003cli\u003eHeat exchanger: 2-row 42mm B-Tube, 6.5mm fins, integrated rock guard\u003c\/li\u003e\n\u003cli\u003eTrans cooler: dual-core, 201 percent more volume, 16mm 9-channel microtube (15 tubes, 16 rows)\u003c\/li\u003e\n\u003cli\u003eEngine: S58 twin-turbo 3.0L (also B58 M40i, after 08\/2019)\u003c\/li\u003e\n\u003cli\u003eConstruction: 100 percent all-aluminum TIG-welded; hand-brushed satin\u003c\/li\u003e\n\u003cli\u003eFitment: plug-and-play drop-in (M40i may need minor line adjustment)\u003c\/li\u003e\n\u003cli\u003ePart number: 8331\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle Applications\u003c\/h3\u003e\u003cp\u003eDirect fit on the following (S58 twin-turbo; also fits B58 X3 M40i \/ X4 M40i built after 08\/2019):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2020 BMW X3 M (F97)\u003c\/li\u003e\n\u003cli\u003e2021 BMW X3 M (F97)\u003c\/li\u003e\n\u003cli\u003e2022 BMW X3 M (F97)\u003c\/li\u003e\n\u003cli\u003e2023 BMW X3 M (F97)\u003c\/li\u003e\n\u003cli\u003e2024 BMW X3 M (F97)\u003c\/li\u003e\n\u003cli\u003e2020 BMW X4 M (F98)\u003c\/li\u003e\n\u003cli\u003e2021 BMW X4 M (F98)\u003c\/li\u003e\n\u003cli\u003e2022 BMW X4 M (F98)\u003c\/li\u003e\n\u003cli\u003e2023 BMW X4 M (F98)\u003c\/li\u003e\n\u003cli\u003e2024 BMW X4 M (F98)\u003c\/li\u003e\n\u003cli\u003e2025 BMW X4 M (F98)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the CSF 8331 fit?\u003c\/h5\u003e\u003cp\u003eThe 2020-2024 BMW F97 X3 M and 2020-2025 F98 X4 M with the S58 engine; it also fits the G01 X3 M40i and G02 X4 M40i (B58) built after 08\/2019.\u003c\/p\u003e\u003ch5\u003eWhat does the module combine?\u003c\/h5\u003e\u003cp\u003eThe heat exchanger and transmission oil cooler in a single integrated unit.\u003c\/p\u003e\u003ch5\u003eHow much bigger is the transmission cooler?\u003c\/h5\u003e\u003cp\u003eA dual-core design with 201 percent more core volume than OEM.\u003c\/p\u003e\u003ch5\u003eIs it a drop-in fit?\u003c\/h5\u003e\u003cp\u003eYes for the M models; M40i cars may need minor line-positioning adjustment.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What vehicles does the CSF 8331 fit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The 2020-2024 BMW F97 X3 M and 2020-2025 F98 X4 M with the S58 engine; it also fits the G01 X3 M40i and G02 X4 M40i (B58) built after 08\/2019.\"}}, {\"@type\": \"Question\", \"name\": \"What does the module combine?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The heat exchanger and transmission oil cooler in a single integrated unit.\"}}, {\"@type\": \"Question\", \"name\": \"How much bigger is the transmission cooler?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A dual-core design with 201 percent more core volume than OEM.\"}}, {\"@type\": \"Question\", \"name\": \"Is it a drop-in fit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes for the M models; M40i cars may need minor line-positioning adjustment.\"}}]}\u003c\/script\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":42636395511856,"sku":"CSF8331","price":1289.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0586\/9548\/3440\/files\/8358e62e7821a404d6330fc701247b7eL.jpg?v=1765305359","url":"https:\/\/berryperformancesales.com\/products\/csf-cooling-module-heat-exchanger-trans-cooler-bmw-f9x-x3m-x4m-8331","provider":"Berry Performance Sales","version":"1.0","type":"link"}
