About this part

Product Details

You're getting a Mishimoto performance heat exchanger specifically made for the 2023 through 2025 Nissan Z. This part is designed to help keep your Z's charge air cooling system running at its best, especially when you're pushing the car hard.

This heat exchanger offers a significant upgrade over the stock unit. It boasts a 172 percent larger core volume, which means it can remove more heat from the coolant more effectively. In testing, this resulted in outlet coolant temperatures that were 10 degrees cooler than stock, even after repeated heat cycles. It also reduces the pressure drop across the system by 2 psi, making it less restrictive and easier on your water pump. The end tanks are made from durable aluminum, which should hold up better over time than the stock plastic ones. Mishimoto also kept the factory rock guard mounting points so you can reuse it for added protection against road debris.

Installation is straightforward as this unit is a direct fit for your Z, meaning no other modifications are needed. There's even a conveniently placed air bleed port that lets you get all the air out of the system easily, even with the bumper still on. This heat exchanger comes with Mishimoto's Lifetime Warranty for peace of mind.
