CSF 09-20 Nissan 370Z / 08-13 Infiniti G37 (MT) Triple-Pass Radiator + AC Condenser

With over five decades of dedicated expertise in radiator manufacturing, CSF stands as a leader in delivering superior cooling solutions for high-performance vehicles. The CSF 09-20 Nissan 370Z / 08-13 Infiniti G37 (MT) Triple-Pass Radiator + AC Condenser is engineered to meet the rigorous demands of both street driving and competitive motorsports environments. This product exemplifies CSF’s commitment to quality, reliability, and precision engineering, ensuring your vehicle operates at optimal temperatures even under the most challenging conditions.

The hallmark of this radiator is its innovative Triple-Pass Flow Structure, a design that directs coolant through the radiator core three times before exiting. This mechanism significantly reduces outlet temperatures, providing enhanced cooling efficiency that is critical for high horsepower builds and race vehicles. The radiator’s 2-Row 42mm core incorporates CSF’s exclusive B-Tube Technology, a distinctive feature that sets it apart from conventional radiators.

Unlike traditional oval-shaped “O” tubes, CSF’s B-Tubes are meticulously engineered in a “B” shape and brazed over the seam to create an exceptionally strong and lightweight structure. This design allows the use of thinner aluminum material without compromising durability, resulting in improved cooling performance. The B-Tube’s unique inlet positioned in the middle of the tube increases the heat transfer surface area by approximately 15% compared to standard tubes, effectively doubling the heat dissipation capacity within the same spatial constraints. This dual liquid laminar flow enhances thermal efficiency, making the radiator highly effective in managing engine temperatures.

Complementing the advanced tube design, CSF employs ultra-efficient multi-louvered fins that are precisely aligned to maximize airflow through the radiator core. The fin specifications have been carefully calculated and tested in CSF’s wind-tunnel laboratory to ensure maximum heat rejection efficiency. This meticulous attention to detail guarantees that the radiator performs reliably under both everyday and high-stress conditions.

Installation is streamlined with a true “Drop-in Fit” design, requiring no modifications to your vehicle. The radiator includes CNC-machined and welded OE-style brackets that provide exceptional durability and secure mounting. Additionally, the inlet and outlet connections are engineered to match original equipment manufacturer (OEM) specifications, allowing seamless reuse of OEM hoses or compatible aftermarket components. This ensures a straightforward installation process and maintains the integrity of your vehicle’s cooling system.
