Description
The Mishimoto Universal Air-to-Water Heat Exchanger (MMRAD-HE-02) is a purpose-built, three-row aluminum core designed to pull heat out of your air-to-water intercooler circuit before it ever reaches the charge-air cooler. Rated to provide effective cooling support for charge-air cooling systems up to 750 hp, this heat exchanger is engineered for forced-induction builds that demand consistent coolant temperatures under boost. It’s one of four universal Mishimoto heat exchangers – each scaled to support builds up to 1,500 hp – with the MMRAD-HE-02 offering a 3-row core configuration for serious street and track applications.
Built entirely from TIG-welded aluminum, this Mishimoto cooling component is engineered to handle the pressure and heat cycling that come with high-boost, liquid-to-air intercooling setups. Its strategically designed 3-row cross-flow core is aimed at maximizing flow and heat dissipation, while bead-rolled 3/4-in inlet and outlet fittings promote leak-free connections to your existing plumbing. Robust 1/2-in thick threaded mounting bosses on each end tank simplify installation into a custom air-to-water intercooler system, and because it’s a universal-fit heat exchanger, it can be integrated into a wide variety of turbocharged builds rather than being tied to one specific vehicle. Backed by the Mishimoto Lifetime Warranty, this heat exchanger is built to serve as a long-term centerpiece of your charge-air cooling system.
Vehicle Applications
The Mishimoto MMRAD-HE-02 Air-to-Water Heat Exchanger is a universal-fit cooling component rather than a vehicle-specific part – no particular make, model, chassis, or engine code is required for installation. It is designed to be plumbed into any custom air-to-water intercooler system, making it suitable for turbocharged builds across a wide range of platforms where a liquid-to-air heat exchanger is needed to support charge-air cooling up to 750 hp.
