The triangular design does not affect the heat dissipation effect, but also has good stability, preventing the radiator from damage and leakage due to collision, and prolonging the service life of the radiator.Description:This aluminum radiator is designed to provide maximum cooling efficiency to prevent premature engine failure.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.This Aluminum Radiator is at least 40% 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.
