This Koyo aluminum racing radiator is designed to be direct factory replacement unit. What makes these more effective than stock radiators is it is a much thicker core, a more efficient fin design that helps with flow, and temperature drop over the surface. This Koyo radiator is roughly 20mm thicker than stock, allowing for larger capacity, better flow, and faster heat loss over the surface of the core.
