CSF Mitsubishi Evo 7/8/9 Full Size Slim All-Aluminum Radiator w/ 12in SPAL Fan

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions tailored for the Mitsubishi Evo 7/8/9 series. The CSF Mitsubishi Evo 7/8/9 Full Size Slim All-Aluminum Radiator with a 12-inch SPAL Fan exemplifies the pinnacle of engineering excellence, designed to maintain optimal engine temperatures under the most demanding conditions, whether on the street or the racetrack. This radiator is engineered to meet the rigorous demands of high-performance and motorsport environments, where efficient heat dissipation is critical. Featuring a robust 2-row core equipped with CSF’s proprietary B-Tube Technology, this design surpasses conventional oval “O” tubes by utilizing a unique “B”-shaped tube. These tubes are precision-formed and seam-brazed, allowing the use of thinner, lighter aluminum material without compromising structural integrity. The innovative tube shape increases the heat transfer surface area by approximately 15%, effectively delivering the cooling capacity of two smaller tubes within the same spatial footprint. This dual liquid laminar flow enhances thermal efficiency and contributes to superior engine cooling. Complementing the advanced tubing, CSF incorporates ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator core. Each fin’s specifications are carefully calculated and validated through rigorous wind-tunnel testing to ensure maximum heat rejection performance. This attention to detail guarantees that the radiator performs reliably under intense thermal loads. The CSF Evo 7/8/9 radiator is designed as a true drop-in fit solution, requiring no modifications for 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 specifications, allowing seamless integration with OEM hoses or aftermarket alternatives, thus simplifying the upgrade process. Product Details The Mitsubishi Lancer Evolution series is renowned for its versatility as a compact sports sedan, capable of excelling on various road and track conditions. Its rally-inspired engineering offers limitless performance potential, supported by a vast array of aftermarket components. Regardless of the extent of your build—whether mild tuning or aggressive modifications—maintaining effective cooling is essential to preserve engine performance and longevity. Developed in collaboration with Sheepey Built, the Ultimate Evo full-sized slim radiator represents the culmination of extensive research and development. This assembly includes a fully sealed aluminum fan shroud paired with a 12-inch SPAL fan positioned on the driver’s side, delivering maximum cooling efficiency. The radiator incorporates CSF’s exclusive B-Tube technology and multi-louvered fins to optimize heat transfer and airflow. Its design accommodates all turbo configurations, including large forward-facing turbo setups, ensuring versatility across various Evo builds. Additional features include a 1.4 bar high-pressure radiator cap, -16 and slip-on fittings, and all necessary mounting hardware. The radiator is finished with a meticulous 1-hour mirror polish for a striking appearance or an optional satin black coating for a stealthy OEM+ aesthetic. Whether your application involves track racing, drag events, or automotive shows, upgrading to the Ultimate Evo full-sized slim radiator is a strategic investment. By maintaining engine temperatures within optimal operating ranges, this radiator not only preserves peak performance but also extends engine life, ensuring reliability and consistency. For those seeking alternative sizing options, CSF offers the Universal Half Radiator for Evo 7/8/9 (#2858X/2858XB) and the Evo 7/8/9 High-Performance All-Aluminum Half Radiator (#7228/7228B), both engineered as drop-in fit solutions compatible with Evo 7/8/9 setups.
