Mishimoto MMRT-A2W-25N Ice Tank
Best for compact installations where space is at a premium. The MMRT-A2W-25N uses a 2.5-gallon liquid capacity and can hold up to 8 pounds of ice. It’s built with fully TIG-welded aluminum to withstand pressure and corrosion. It is designed to work with internal bilge pumps like Rule 2000 or Rule 3700, or an external pump of your choosing. This makes it a good pick for smaller builds or budget-conscious enthusiasts who still want solid ice-based cooling. Caution: verify your pump compatibility and mounting options to ensure a clean installation.
Who it’s best for: Riders with limited space, lower ice capacity needs, and a DIY pump setup. It’s also suitable for those who want a lighter, modular ice tank that can be paired with various external pumps.
GPI RACING Air to Water Intercooler Heat Exchanger Radiator
This universal heat exchanger focuses on a larger core suitable for higher-boost scenarios. Core size is 24″ × 7 3/4″ × 2 1/4″, with an overall length of about 31 3/8″ × 9″ × 3 7/8″. It’s best for users who can confirm fitment before purchase and want a bigger radiator-style exchanger to maximize heat transfer. Caution: check whether your vehicle has the necessary mounting space and compatible fan setup.
Who it’s best for: Enthusiasts needing a big, adaptable exchanger for bigger intercooler systems or universal installs where space permits.
Mishimoto MMRT-A2W-50N Ice Tank
Best for performance builds needing larger ice reserves. The 5.0-gallon version expands cooling capacity and features universal compatibility for ice tank-equipped air-to-water systems. It uses durable TIG-welded aluminum construction to resist pressure and corrosion over time. A clear advantage is the significant ice/water reserve, which helps maintain lower intake air temperatures under sustained boosts. Caution: ensure the pump and plumbing can handle the increased volume and weight when full of ice.
Who it’s best for: Performance-oriented applications seeking longer cooling duration and higher IAT reduction without frequent recharges.
POWERSR Universal Air to Water Intercooler Heat Exchanger
This universal unit emphasizes lightweight, direct bolt-on OEM-like fitment, suitable for a range of models. The core and aluminum construction aim to deliver effective heat dissipation with straightforward installation. It’s a solid choice for drivers who want a balance of ease-of-installation and performance. Caution: “universal” fitment may require brackets or adapters for your specific vehicle, and professional installation can help ensure proper sealing and mounting.
Who it’s best for: Builders seeking a straightforward upgrade path that resembles an original-component installation while improving heat transfer efficiency.
Buying Guide
What should you consider before buying?
Heat exchanger size and capacity, ice tank volume, and pump compatibility all influence performance. A larger core typically provides better heat transfer but may require more space and a stronger pump. Ice tank capacity matters for sustained cooling during hard driving sessions. Ensure your vehicle has compatible mounting points, electrical needs, and space for plumbing. Consider whether you want a plug-and-play unit or a modular system you assemble with a pump of your choice.
Which kit is best for your setup?
Choose this if you want maximum cooling duration with a large ice reserve (MMRT-A2W-50N). Pick this for space-constrained builds that still demand decent cooling (MMRT-A2W-25N). Opt for a universal exchanger when you need broad compatibility and a big core (GPI RACING unit). For easier installation with an OEM-like fit, the POWERSR exchanger is a practical pick. If you’re upgrading a high-boost turbo or supercharged setup, the Ferncaot unit offers a direct replacement-style option with solid heat transfer properties.
Installation considerations
- Professional installation is recommended for complex coolant plumbing.
- Check for leaks, compatibility with your cooling system, and pump flow requirements.
- Verify fitment in your engine bay or front-end area before purchasing any larger core units.
FAQ
- What is an air-to-water intercooler kit? It uses a liquid coolant loop to absorb heat from the intake air, reducing temperatures and improving performance under sustained boost.
- Do I need a specific ice tank size? Larger tanks provide longer cooling duration but require more space and weight considerations in the vehicle.
- Is universal fitment reliable? Universal units offer broad compatibility but may require brackets or custom mounting for a secure fit.
- Can I install this myself? Some kits are designed for DIY installation, while others benefit from professional mounting to ensure proper sealing and pump integration.
- Will this affect engine reliability? Properly designed and installed intercoolers can reduce heat soak, which may improve performance consistency under boost.
- Which kit provides the best value? Value depends on space, desired cooling duration, and the complexity you’re willing to manage during installation.
