The CSF 02-07 Impreza WRX\/STI All-Aluminum Radiator, equipped with a built-in oil cooler, exemplifies this legacy by delivering superior cooling performance tailored specifically for the Subaru WRX and STI models from 2002 to 2007. Engineered for both street and track applications, this radiator is an essential component for high-performance builds and motorsport vehicles that demand enhanced thermal management under rigorous conditions.\u003c\/p\u003e\n\n\u003cp\u003eAt the core of this radiator’s advanced design lies CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, the B-Tube features a unique “B” cross-sectional profile that is meticulously formed and seam-brazed to ensure structural integrity. This innovative approach allows the use of thinner, lighter aluminum material while simultaneously increasing cooling efficiency. The B-Tube’s design enhances the heat transfer surface area by approximately 15% compared to standard tubes, effectively doubling the heat dissipation capacity within the same spatial constraints. This results in a dual liquid laminar flow, optimizing coolant movement and heat rejection.\u003c\/p\u003e\n\n\u003cp\u003eComplementing the B-Tube technology, the radiator incorporates ultra-efficient multi-louvered fins with a precise 6.5mm fin height. These fins are carefully aligned to maximize airflow through the core, ensuring optimal heat exchange. Each fin specification is rigorously calculated and validated in CSF’s wind tunnel laboratory, guaranteeing peak performance and reliability.\u003c\/p\u003e\n\n\u003cp\u003eThe CSF WRX\/STI radiator is designed as a true “drop-in fit” solution, requiring no modifications during installation. All original equipment (OE) style brackets are CNC machined and welded to provide exceptional durability and precise fitment. The inlet and outlet connections are engineered to match OE standards, allowing seamless integration with OEM hoses or aftermarket components. This meticulous attention to detail ensures that the radiator not only performs at a high level but also maintains compatibility and ease of installation.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n \u003cli\u003e2-Row 42mm Core (Dual Core) featuring CSF’s proprietary B-Tube Technology for enhanced heat transfer\u003c\/li\u003e\n \u003cli\u003eUltra-efficient multi-louvered fins with 6.5mm fin height, optimized for maximum surface area and airflow\u003c\/li\u003e\n \u003cli\u003eCNC machined “quick-connect” inlet and outlet connections for secure and precise hose attachment\u003c\/li\u003e\n \u003cli\u003eCNC machined brackets and fittings ensuring superior fit, strength, and long-term durability\u003c\/li\u003e\n \u003cli\u003eAll-aluminum race-style drain plug designed for efficient coolant drainage and maintenance\u003c\/li\u003e\n \u003cli\u003e1-hour “mirror finish” hand polish enhancing corrosion resistance and aesthetic appeal\u003c\/li\u003e\n \u003cli\u003e“Drop-in fit” design compatible with all OEM components including quick connect hoses, AC condenser, mounting brackets, and fan shroud\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003ctable\u003e\n \u003cthead\u003e\n \u003ctr\u003e\n \u003cth\u003eYear Range\u003c\/th\u003e\n \u003cth\u003eMake\u003c\/th\u003e\n \u003cth\u003eChassis Code\u003c\/th\u003e\n \u003cth\u003eModel\u003c\/th\u003e\n \u003cth\u003eTrim\u003c\/th\u003e\n \u003cth\u003eEngine \/ Trans \/ Etc\u003c\/th\u003e\n \u003cth\u003eNotes\u003c\/th\u003e\n \u003c\/tr\u003e\n \u003c\/thead\u003e\n \u003ctbody\u003e\n \u003ctr\u003e\n \u003ctd\u003e2002-2005\u003c\/td\u003e\n \u003ctd\u003eSubaru\u003c\/td\u003e\n \u003ctd\u003eGD\/GG\u003c\/td\u003e\n \u003ctd\u003eImpreza\u003c\/td\u003e\n \u003ctd\u003eWRX\u003c\/td\u003e\n \u003ctd\u003eTurbocharged 2L H4 (Manual)\u003c\/td\u003e\n \u003ctd\u003e-\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003e2006-2007\u003c\/td\u003e\n \u003ctd\u003eSubaru\u003c\/td\u003e\n \u003ctd\u003eGD\/GG\u003c\/td\u003e\n \u003ctd\u003eImpreza\u003c\/td\u003e\n \u003ctd\u003eWRX\u003c\/td\u003e\n \u003ctd\u003eTurbocharged 2.5L H4 (Manual)\u003c\/td\u003e\n \u003ctd\u003e-\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003e2004-2007\u003c\/td\u003e\n \u003ctd\u003eSubaru\u003c\/td\u003e\n \u003ctd\u003eGD\/GG\u003c\/td\u003e\n \u003ctd\u003eImpreza\u003c\/td\u003e\n \u003ctd\u003eWRX STI\u003c\/td\u003e\n \u003ctd\u003eTurbocharged 2.5L H4 (Manual)\u003c\/td\u003e\n \u003ctd\u003e-\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch5\u003eOEM Part Numbers\u003c\/h5\u003e\n\u003cul\u003e\n \u003cli\u003eSubaru: 45111FE000\u003c\/li\u003e\n \u003cli\u003eSubaru: 45119FE000\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eWarranty Information\u003c\/h5\u003e\n\u003cp\u003eCooling Systems and Flexibles, Inc.
