Description
The Mishimoto MMUIC-W4 is a universal air-to-water race intercooler core measuring 12.00in x 5.90in x 5.90in, engineered as a standalone core for builders assembling their own forced induction intercooler setup. As a dedicated Mishimoto Forced Induction component, this core is designed to serve as the heart of a custom air-to-water charge cooling system rather than a bolt-in kit for a specific vehicle.
Air-to-water intercooling is a proven approach for demanding forced induction applications where consistent charge temperatures matter under sustained boost. By using water as the cooling medium instead of ambient airflow alone, an air-to-water core like this Mishimoto unit can be packaged into tighter engine bays or unconventional induction system layouts where a traditional air-to-air core won’t fit. This makes it a popular choice among builders designing a custom forced induction system, performance induction setup, or force induction race application that calls for a compact, high-density core rather than a full assembly.
Vehicle Applications
This Mishimoto MMUIC-W4 core is sold as a universal component and is not tied to a specific make, model, or year. It is intended for builders and fabricators integrating an air-to-water intercooler core into a custom forced induction or induction system build, giving flexibility for a wide range of race and performance projects where a fixed-fitment intercooler core would not work.
