From the Japanese site. Hadnt seen this detail before
Five cooling systems are installed, including a water-cooled intercooler, radiator, and oil cooler to support the high output of 405PS. The air flow rate is secured to improve the cooling performance, and the front grille has a Tear Drop cross section. It also reduces air resistance and front lift. In addition, we have created a form that makes you feel like a Fairlady Z, achieving both functionality and design.
