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.
