Following the success of CSF's industry-leading Front Mount Heat Exchanger for the W205 AMG, this Auxiliary Radiator expands that same cooling philosophy across the wider platform. These auxiliary radiators do double duty, helping keep engine coolant temperatures lower while also serving as the heat exchange medium for the air-to-water charge air coolers on the turbocharger system, directly reducing intake air temperatures.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eBy increasing core thickness from the OEM's 26mm to a full 42mm, this unit delivers approximately \u003cstrong\u003edouble the fluid capacity\u003c\/strong\u003e of the factory design, genuinely prolonging the heat soak threshold on street or track. The 2-row, high-performance core uses CSF's proprietary B-Tube technology, paired with ultra-efficient 6.5mm tall multi-louvered fins for maximum surface area contact. A genuinely practical touch: this unit is multi-fit and works on either the left or right side, and it includes a detachable rock guard for protection against debris and core punctures, unlike the OEM units, which have little protection against the elements.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eImportant fitment note:\u003c\/strong\u003e because this radiator is approximately 1 inch (25mm) thicker than the factory unit, C63 models fitted with larger wheels (such as 20\") may require the rear plastic duct\/shroud to be trimmed by roughly that amount. AMG GT models may require the rear duct\/shroud to be trimmed or removed entirely.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy Choose This Auxiliary Radiator\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eApproximately 100% more fluid capacity than OEM (26mm OEM core vs 42mm CSF core)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReduces both engine coolant and charge-air cooler intake air temperatures\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMulti-fit design works on either the left or right side\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIncludes a detachable rock guard, genuine protection the OEM unit lacks\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e2-row core with CSF's proprietary B-Tube technology and 6.5mm multi-louvered fins\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e2-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eCompatibility\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMercedes-AMG C63\/C63S (W205, M177)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMercedes-AMG GLE63\/GLE63S (W166)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMercedes-AMG GLS63 (X166)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e CSF recommends replacing both left and right auxiliary radiators together on vehicles equipped with two from the factory.
