The factory setup works fine under mild conditions and stock power, but quickly becomes a limiting factor during aggressive driving, causing heat soak and robbing power. The AMS Heat Exchanger solves this with a 35% larger core and a dramatically more efficient design — the largest drop-in unit on the market, requiring no cutting or modification.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e35% larger core volume than OEM — the largest drop-in unit on the market\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency, dual-pass, motorsport-grade core design\u003c\/li\u003e\n\u003cli\u003eDouble the coolant capacity of the OEM unit for greater thermal stability\u003c\/li\u003e\n\u003cli\u003eCNC-machined billet 6061 T6 aluminum end tanks for precise, clean OEM-level fitment\u003c\/li\u003e\n\u003cli\u003eRadiused coolant inlet\/outlet fittings reduce pressure drop for smoother flow\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on install using factory mounting points — no cutting, trimming, or drilling\u003c\/li\u003e\n\u003cli\u003eValidated on-track with time attack racer Jackie Ding (Gridlife\/Super Lap Battle): 112.8°F peak intercooler air outlet temp vs. 116.4°F stock and 120.2°F for the leading competitor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFully assembled direct-fit S58 heat exchanger\u003c\/li\u003e\n\u003cli\u003eInstallation hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRecommended companion: \u003ca href=\"\/products\/ams-performance-bmw-g8x-m2-m3-m4-s58-intakes\"\u003eAMS G8X S58 Intakes\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstall instructions (PDF): \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/AMS-Performance-BMW-G8X-M2-M3-M4-S58-Heat-Exchanger-Install-Instructions-2025-1-20.pdf?v=1785460190\" target=\"_blank\" rel=\"noopener\"\u003eAMS G8X S58 Heat Exchanger Install Guide\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstall\/overview video: \u003ca href=\"https:\/\/www.youtube.com\/watch?v=EgR6dCamsIA\" target=\"_blank\" rel=\"noopener\"\u003eAMS G8X S58 Heat Exchanger (YouTube)\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAMS.48.02.0001-1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM2 (incl. all sub-models)\u003c\/td\u003e\n\u003ctd\u003eG87\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2023+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM3 (incl. all sub-models)\u003c\/td\u003e\n\u003ctd\u003eG80\/G81\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2021+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003eM4 (incl. all sub-models)\u003c\/td\u003e\n\u003ctd\u003eG82\/G83\u003c\/td\u003e\n\u003ctd\u003eS58\u003c\/td\u003e\n\u003ctd\u003e2021+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AMS Performance","offers":[{"title":"Standard","offer_id":53627877261619,"sku":"AMS.48.02.0001-1","price":699.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/4226\/2579\/files\/AMS-Performance-BMW-G8X-M2-M3-M4-Heat-Exchanger-1.jpg?v=1783458124","url":"https:\/\/x58cartel.com\/products\/ams-performance-bmw-g8x-m2-m3-m4-s58-heat-exchanger","provider":"x58cartel","version":"1.0","type":"link"}
