JDC Coolant Expansion Tank

The JDC Coolant Expansion Tank is exactly what your GT-R should have come with from the factory. The ugly plastic yellow tank is an eyesore and must go! This tank is made from 6061 aluminum and is powder coated satin black for a super clean look! The tank is easy to install with the included titanium hardware and reuses the factory hoses. It includes a cap that comes with our beautiful titanium badge for that final touch! We've also thrown in an additional cap cover to add to the thermostat housing cap so they both match!
