Water to Air Intercooler Cores 12inW x 4inH x 4

The Water to Air Intercooler Cores 12inW x 4inH x 4 from VIBRANT PERFORMANCE is engineered for serious turbocharged and supercharged vehicle builders seeking maximum cooling efficiency in a compact footprint. These cores are purpose-built for custom water-to-air intercooler systems, where intake charge temperature directly impacts horsepower output and engine reliability. Whether you're building a high-performance street car, track vehicle, or engine swap project, this core provides the thermal capacity needed to keep boost temperatures in check and maintain optimal fuel mapping across the RPM range.

Constructed with premium aluminum bar-and-plate design, the Water to Air Intercooler Cores features an efficient internal fin geometry that maximizes heat transfer surface area while minimizing pressure drop across the coolant circuit. The 12-inch width, 4-inch height, and 4-inch depth dimensions deliver a high core density suitable for custom mounting in engine bays where space is limited, yet maintains the flow rate necessary for effective heat rejection. VIBRANT PERFORMANCE's precision manufacturing ensures tight tolerances on all inlet and outlet ports, preventing coolant bypass and guaranteeing consistent performance across varying boost levels and ambient temperatures.

This intercooler core is ideal for LS swap projects, late-model turbocharged platforms, and any application requiring a custom water-cooling loop integration. Fabricators and tuners appreciate the standardized 4-inch depth, which simplifies duct design and radiator stack configurations in tight engine compartments. Installation requires welding aluminum end tanks with appropriate inlet/outlet sizing to your cooling circuit—a straightforward process for experienced builders using proper TIG techniques and aluminum filler materials. Weighing 6.45 lbs, the core is lightweight enough for performance applications while providing industrial-grade durability for street and track use.
