Direct-fit air-to-water heat exchanger for the 2023+ Nissan Z, sized to cool the charge-air system far better than the factory unit. A 172 percent increase in core volume and 39.4 percent more frontal surface area remove more heat from more coolant in less time, producing outlet temperatures roughly 10 degrees cooler than stock in heat-soak testing and cutting pressure drop by 2 psi. Aluminum end tanks replace the stock plastic crimped tanks for durability, and the unit retains the factory rock guard to protect against debris. It installs in the stock location with no other modifications.
