Developed for both 6-speed manual and ZF8 automatic-equipped vehicles, the upgraded heat exchanger increases cooling capacity and improves heat-soak recovery during sustained street and track use.\u003c\/p\u003e \u003cp\u003eThe BMW S58 uses a liquid-to-air charge cooling system, with the front-mounted heat exchanger responsible for removing heat from the coolant circulating through the charge-air cooler. As power and sustained load increase, controlling this coolant temperature becomes increasingly important for managing intake air temperatures (IATs) and maintaining consistent engine performance.\u003c\/p\u003e \u003cp\u003eCSF replaces the factory 1-row, 35mm core with a larger 2-row, 42mm core featuring its B-Tube technology. The increased core volume and heat-transfer surface area improve thermal capacity while maintaining airflow to the cooling components positioned behind the heat exchanger. For 2026, CSF updated the design with new Track-Spec 5mm-tall multi-louvered fins to further increase surface-area contact and heat dissipation.\u003c\/p\u003e \u003cp\u003eFor vehicles requiring additional S58 charge-air cooling capacity, the heat exchanger can also be paired with the CSF S58 Charge-Air Cooler Manifold as part of a more comprehensive charge-air cooling system.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDesigned for BMW G87 M2, G80\/G81 M3, and G82\/G83 M4 with the S58 engine\u003c\/li\u003e \u003cli\u003e2-row, 42mm high-performance core compared to the factory 1-row, 35mm core\u003c\/li\u003e \u003cli\u003eCSF B-Tube technology\u003c\/li\u003e \u003cli\u003e2026 Track-Spec 5mm-tall multi-louvered fin design\u003c\/li\u003e \u003cli\u003eDesigned to reduce intake air temperatures (IATs) and improve heat-soak recovery\u003c\/li\u003e \u003cli\u003eImproved airflow to the remaining cooling system\u003c\/li\u003e \u003cli\u003e100% all-aluminum TIG-welded construction\u003c\/li\u003e \u003cli\u003eCNC-machined mounting brackets\u003c\/li\u003e \u003cli\u003eOEM-style quick-connect inlet and outlet\u003c\/li\u003e \u003cli\u003eDirect drop-in installation with no vehicle modifications required\u003c\/li\u003e \u003cli\u003eIncludes application-specific Black Rock Guard and transmission cooler mounting hardware\u003c\/li\u003e \u003cli\u003eCompatible with 6-speed manual and ZF8 automatic transmission applications\u003c\/li\u003e \u003cli\u003e2-year limited warranty\u003c\/li\u003e \u003cli\u003eCSF #8215\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e6-speed manual applications include upper and lower Black Rock Guards.\u003c\/li\u003e \u003cli\u003eZF8 automatic applications include the upper Black Rock Guard and transmission cooler mounting kit.\u003c\/li\u003e \u003cli\u003eFor ZF8-equipped vehicles, CSF developed the heat exchanger core specifications alongside its Race-Spec Dual Core Transmission Oil Cooler.\u003c\/li\u003e \u003c\/ul\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":67981391298714,"sku":"8215","price":729.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/7569\/3466\/files\/52360243875_f16a8d7ea1_b.jpg?v=1793133501","url":"https:\/\/apexmotorsportswa.com\/products\/csf-g8x-m2-m3-m4-s58-high-performance-front-mount-heat-exchanger","provider":"Apex Motorsport","version":"1.0","type":"link"}
