Description
The Mishimoto MMUIC-W3 is a universal air-to-water race intercooler core measuring 12.00in x 4.92in x 4.92in, engineered by Mishimoto as a dedicated Forced Induction component for builders who need a compact, high-capacity core rather than a complete off-the-shelf kit. As a bare core, it gives fabricators the freedom to design end tanks, plumbing, and mounting solutions around their own forced induction system layout.
Air-to-water intercooling is a proven approach for serious forced induction turbo builds, race cars, and other projects where space is tight but heat rejection demands remain high. Because this Mishimoto core is sold as a universal piece rather than a vehicle-specific assembly, it suits a wide range of custom induction system projects, from track-focused builds to boosted engine swaps, giving tuners and fabricators a solid foundation for their own forced induction interchiller or water-to-air intercooling setup. Its compact 12.00in x 4.92in x 4.92in footprint makes it a practical option where packaging space around the engine bay or custom mounting location is limited.
Vehicle Applications
The Mishimoto MMUIC-W3 air-to-water race intercooler core is a universal component and is not tied to a specific make, model, or year. It is intended for fabricators and builders who are designing their own custom forced induction system, air-to-water intercooler kit, or turbo installation and need a race-capable core sized to fit within their own tank and plumbing design.
