Mishimoto Performance Heat Exchanger for 2023-2025 Nissan Z (MMHE-Z-23)

Fits 2023-2025 Nissan Z Sport, Performance, Nismo, and Proto Spec models. The Mishimoto performance heat exchanger is designed to manage the high thermal loads of the VR30DDTT engine, providing a significant upgrade over the restrictive factory unit.

By increasing core volume by 172% and frontal surface area by 39.4%, this heat exchanger provides superior thermal transfer. During testing, these improvements resulted in outlet coolant temperatures 10°F cooler than stock. Beyond temperature management, this unit reduces pressure drop by 2 psi, decreasing the load on the factory charge air cooling water pump and improving overall system efficiency.

Built for long-term durability, Mishimoto replaces the failure-prone plastic factory end tanks with robust, TIG-welded aluminum tanks. For ease of maintenance, a strategically placed air bleed port allows you to purge the system of air without removing the front bumper. This is a direct-fit component that retains the factory rock guard for maximum protection against road debris.
