CSF 03-07 Mitsubishi Lancer (Evolution 7/8/9) High-Performance All-Aluminum Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-performance cooling solutions tailored for demanding automotive applications. The CSF 03-07 Mitsubishi Lancer (Evolution 7/8/9) High-Performance All-Aluminum Radiator exemplifies this commitment to quality and engineering excellence. Engineered specifically to optimize cooling efficiency for the Mitsubishi Lancer Evolution series, this radiator ensures your engine maintains optimal operating temperatures under both street and track conditions.

Designed to meet the rigorous demands of high horsepower builds and motorsports environments, this radiator incorporates advanced technology and precision craftsmanship. Central to its superior performance is CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped "O" tubes, the B-Tube features a unique "B" shape that is carefully formed and seam-brazed to enhance structural integrity. This innovative design allows the use of thinner, lighter aluminum material without compromising strength, resulting in improved cooling efficiency.

The B-Tube design increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling performance of two smaller tubes within the same spatial constraints. This dual liquid laminar flow capability enhances heat dissipation, making it ideal for vehicles subjected to intense thermal loads. Complementing this design are ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator core. Each fin specification is precisely engineered and validated through rigorous wind-tunnel testing to guarantee maximum heat rejection efficiency.

The radiator features a robust 2-Row 42mm core, providing an optimal balance between cooling capacity and compactness. The CNC-machined inlet and outlet connections are designed to match original equipment specifications, allowing seamless integration with OEM hoses or aftermarket alternatives. Additionally, the CNC-machined brackets and fittings ensure exceptional fitment and durability, supporting a straightforward installation process without the need for modifications.

CSF’s attention to detail extends to the finishing touches; the radiator undergoes a one-hour "mirror finish" hand polish, enhancing corrosion resistance and aesthetic appeal. The inclusion of an all-aluminum race-style drain plug further underscores the product’s focus on durability and ease of maintenance.

This radiator is a true "drop-in fit" replacement for the Mitsubishi Lancer Evolution models from 2003 through 2007, including Evolution 7, 8, and 9 variants. It supports all attaching OEM components such as quick-connect hoses, AC condenser, mounting brackets, and fan shroud, ensuring compatibility and preserving factory assembly standards.
