The CSF 02-07 Subaru Impreza WRX\/STI All-Aluminum Radiator, finished in black and equipped with a filler neck, embodies the pinnacle of performance and reliability for your vehicle’s cooling system. Engineered to meet the rigorous demands of both street driving and competitive motorsports, this radiator is an essential upgrade for high horsepower builds and race-prepared vehicles requiring enhanced thermal management.\u003c\/p\u003e\n\n\u003cp\u003eAt the core of this radiator’s superior performance is CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, CSF utilizes a uniquely engineered “B” shaped tube that is seam-brazed for exceptional strength and durability. This innovative design allows the use of thinner, lighter aluminum material without compromising structural integrity, resulting in improved cooling efficiency. The B-Tube’s construction increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively delivering the cooling capacity of two smaller tubes within the same spatial constraints. This design also facilitates dual liquid laminar flow, optimizing coolant circulation for maximum heat dissipation.\u003c\/p\u003e\n\n\u003cp\u003eComplementing the advanced core design are ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator. Each fin’s dimensions and orientation are precisely calculated and validated through rigorous wind-tunnel testing to ensure optimal heat rejection performance. The 2-row, 42mm core construction balances cooling capacity with compactness, making it ideal for the Subaru Impreza WRX and STI models without requiring modifications.\u003c\/p\u003e\n\n\u003cp\u003eThe CSF radiator is engineered as a true drop-in replacement, ensuring seamless installation with no need for alterations. All mounting brackets are CNC machined and welded to provide exceptional durability and precise fitment. Inlet and outlet connections are designed to match original equipment manufacturer (OEM) specifications, allowing the use of existing OEM hoses or compatible aftermarket components. This attention to detail guarantees compatibility with all attaching OEM parts, including quick-connect hoses, AC condensers, mounting brackets, and fan shrouds.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n  \u003cli\u003e2-Row 42mm Core (Dual Core) incorporating CSF’s exclusive B-Tube Technology for enhanced heat transfer efficiency\u003c\/li\u003e\n  \u003cli\u003eCore equipped with ultra-efficient fins featuring a 6.5mm fin height and multi-louvered design to maximize surface area contact and airflow\u003c\/li\u003e\n  \u003cli\u003eCNC machined quick-connect inlet and outlet connections for precise fit and ease of installation\u003c\/li\u003e\n  \u003cli\u003eCNC machined brackets and fittings engineered for superior fitment and long-lasting durability\u003c\/li\u003e\n  \u003cli\u003eAll-aluminum race-style drain plug designed for efficient coolant drainage and maintenance\u003c\/li\u003e\n  \u003cli\u003eBlack finish providing a high-end, stealth aesthetic that complements the vehicle’s engine bay\u003c\/li\u003e\n  \u003cli\u003eTrue drop-in fit requiring no modifications, 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\u003e2004-2006\u003c\/td\u003e\n      \u003ctd\u003eSubaru\u003c\/td\u003e\n      \u003ctd\u003e-\u003c\/td\u003e\n      \u003ctd\u003eBaja\u003c\/td\u003e\n      \u003ctd\u003e-\u003c\/td\u003e\n      \u003ctd\u003e2.5L H4 (Manual)\u003c\/td\u003e\n      \u003ctd\u003e-\u003c\/td\u003e\n    \u003c\/tr\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\u003c\/h5\u003e\n\u003cp\u003eCooling Systems and Flexibles, Inc.
