Description
The Mishimoto MMUIC-03 is a universal air-to-air race intercooler core built for enthusiasts and shops designing their own forced induction system rather than bolting on a factory-shaped unit. Measuring a generous 26in x 12in x 4in, this bare core gives builders the raw cooling surface area needed to fabricate a custom end-tank intercooler for a race car, swap project, or performance induction platform.
As a dedicated Forced Induction component, the MMUIC-03 core is the foundation piece behind countless custom intercooler builds. Because it ships as a universal core rather than a vehicle-specific kit, it gives fabricators, tuners, and race teams the flexibility to design their own end tanks, piping, and mounting solution around a proven Mishimoto air-to-air core. Whether you’re upgrading an existing forced induction system, building a one-off induction system for a race application, or replacing a tired core in a custom setup, the MMUIC-03’s 26in x 12in x 4in footprint offers the large surface area builders look for when maximizing charge-air cooling potential in a forced induction turbo application.
Vehicle Applications
The Mishimoto MMUIC-03 is sold as a universal air-to-air race intercooler core and is not tied to a specific make, model, or year. It is intended for custom fabrication work where a builder will design and weld or fabricate their own end tanks and piping to integrate the core into a particular vehicle’s forced induction system, making it a flexible choice for custom race, swap, and performance induction projects.
