Description
The Mishimoto MMRAD-HE-04 Universal Air-to-Water Heat Exchanger is a dual-pass, 2-row aluminum core built specifically to reduce coolant temperature before it reaches the intercooler in a liquid-to-air charge-air cooling setup. With a core measuring 24.60 in x 19.66 in x 1.88 in and an overall footprint of 29.38 in x 20.53 in x 2.51 in, this is one of four universal Mishimoto heat exchangers engineered to support forced-induction builds making up to 1,500 hp.
For anyone planning a turbocharged, air-to-water intercooler system, the heat exchanger is the component that pulls heat out of the coolant loop before it circulates through the intercooler, and cutting corners here can undermine the rest of the charge-air cooling package. Mishimoto’s approach to this Cooling category product uses an all-aluminum, TIG-welded core and end-tank assembly for strength under pressure, a cross-flow design with a Top Right inlet and Bottom Right outlet, and a dual-pass, 2-row core layout strategically designed for maximum flow and heat dissipation. Bead-rolled 3/4-in inlet and outlet connections are built in for a leak-free fit, and half-inch thick threaded mounting bosses on each end tank (mounting point thread size M6x1.0) simplify installation into a custom air-to-water system.
Vehicle Applications
This is a universal heat exchanger rather than a vehicle-specific part, so it is not tied to a particular make, model, or engine code. Instead, it is intended to be installed as part of a custom or aftermarket air-to-water intercooler system on any turbocharged or forced-induction build where a supporting heat exchanger sized for up to 1,500 hp is needed.
