CSF High-Performance All Aluminum Auxiliary Radiators for Mercedes-Benz E63 &

US-BASED SELLER PROFESSIONAL PACKAGING EXPERIENCED CUSTOMER SUPPORT TOP-RATED SELLER CSF High-Performance All Aluminum Auxiliary Radiators for Mercedes-Benz E63 & CLS 63 Brand: CSF | Part Number: 8198 | Condition: NEW Product Description

Upgrade your Mercedes-Benz E63 AMG or CLS 63 with the CSF #8198 High-Performance All Aluminum Auxiliary Radiators. Designed to work seamlessly with your existing cooling system, these radiators help lower engine water temperatures and improve overall thermal management. Their larger capacity prolongs the heat soak threshold, ensuring your vehicle maintains optimal operating temperatures during demanding driving conditions. The radiators also serve as an essential heat exchange medium in the turbocharger\'s air-to-water charge-air coolers, effectively reducing intake air temperatures (IATs) for better turbo performance and engine efficiency. Constructed from 100% TIG-welded aluminum, these radiators feature industry-leading tube and fin technologies, including a 2-row, 68mm high-performance core with exclusive B-Tube technology, providing significantly higher capacity than OEM 1-row 42mm cores. The ultra-efficient multi-louvered fins maximize surface contact for superior heat dissipation.

The CSF Auxiliary Radiators are engineered for a true \"drop-in fit,\" requiring no modifications for installation in the OEM location, making them a straightforward upgrade. CNC-machined mounting brackets and OEM-style \"quick connect\" inlet/outlet fittings facilitate easy installation. Each radiator is individually pressure and leak tested, with a mirror finish hand polish that enhances durability and appearance. The included detachable rock guard offers added protection against debris and potential punctures, unlike OEM units that lack such features. For maximum cooling performance, CSF recommends installing two units—one on each side—along with the front mount heat exchanger for optimal thermal management during intensive driving.

Engineered for durability and efficiency, these radiators are ideal for enthusiasts seeking reliable, high-capacity cooling solutions that withstand demanding conditions while maintaining a clean, professional 68mm High-Performance Core with B-Tube Technology for maximum heat dissipation
