From the factory, your GT-R's engine and transmission share the same inadequate cooling system. Thus, prolonged street abuse or even short stints in racing conditions cause components in the engine and transmission to overheat. This breaks down the engine and transmission oils and will ultimately cause the GT-R to fall into limp mode or shut down. As a solution, our engineering team spent the past year developing, testing and perfecting the most advanced cooling solution for your R35 GT-R.
