Description
The Mishimoto MMUIC-21 is a Universal Air-to-Air Race Intercooler Core sized at 10.5in x 10.4in x 3.5in, engineered as a standalone core for builders who need a compact yet capable air-to-air heat exchanger for a custom forced induction setup. As a universal core rather than a vehicle-specific bolt-on unit, it gives fabricators and race teams the flexibility to design their own end tanks, piping, and mounting solution around a proven Mishimoto core.
Forced induction relies on efficient charge cooling to keep intake air temperatures in check, and this air-to-air core is built to serve as the heart of that induction system. Whether you’re piecing together a forced induction turbo setup for a race car, a project build, or another performance induction application, the MMUIC-21 gives you a dedicated core to integrate into your own intercooler assembly. Because it’s sold as a bare core, it’s a popular choice among builders fabricating a custom forced induction system where off-the-shelf, vehicle-specific intercoolers won’t fit the intended layout or packaging space.
Vehicle Applications
The Mishimoto MMUIC-21 is a universal component, meaning it is not designed as a direct-fit part for a specific make or model. Instead, it is intended for custom installations where a builder is assembling their own forced induction or turbo induction system and needs a race-grade air-to-air core sized to fit within their own end tank and piping design.
