Its light-weight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently. Aluminum Radiator is at least 30%-45% more efficient than stock ones. Most importantly, it has a much higher capacity for coolant than stock ones, which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications. Aircraft aluminum, stronger than other popular alloys and has increased corrosion resistance. Brazed core technology to guarantee optimum performance and dependability. Aluminum 2mm thick tanks and fittings, Ensure it’s hard and durable. Higher density core: cooling rows are spaced 3/8 apart, giving you 25% more rows within the core than other aluminum radiators. 5.14-16 cooling fins per inch, giving you approximately 1500 more cooling fins than other aluminum radiators, throws off much more heat.
