This water to air intercooler kit is superior to air to air intercooler solutions.

Including a high performance water to air intercooler core, a pump, and a radiator (heat exchanger) with fan custom designed for water to air intercooler applications, this kit offers extraordinary value.

The Intercooler Core

This impressive Liquid/Air intercooler is better than any FMIC.

100% Lightweight aluminum, No Epoxy Used In Core

Recommended for over 450 CFM
Pressure Drop: Less than 0.1 PSI. This is not a typo! Liquid/Air Intercoolers have incredibly low pressure drop.
Inlet: 2.5" Outlet: 2.5"
Core Size: 9.25"x3.5"x3.5" (Endtanks add to length)
Maximum water/air pressure: 70 PSI
This intercooler has the inlet and outlet on the SAME SIDE.
Note: The water inlet and outlet on most water/air intercoolers are BPT threads. BPT fittings are difficult to find in the United States, so ours all come with NPT threads. However, the factory erroneously included 1/2" BPT to 3/4" NPS fittings with some of these intercoolers. These fittings will not fit and will strip the threads in the intercooler, do not use them! Please keep them as a free gift and add them to your rusty coffee can full of bolts for later use on another project, and purchase NPT adaptors for use with the intercooler, which are available from us.


Some Water to Air Intercoolers that you can buy online do not contain true water to air cores. A true water to air core has water passages that are much smaller than the air passages. This is part of what allows the water to air intercooler to be so small and have such low pressure drop. Some water to air intercoolers that you buy online use an air to air core design where the air passages for ambient air and intake air are the same size, with an enormous loss of efficiency. Buy from us to make sure that you get a genuine water to air intercooler core!

Water To Air

The Fan

These fans include the mounting kit shown, which is used to secure the fan directly to the radiator through the fins with no additional mounting components.

Why are our universal fans superior to other similar products on the market?

  • Unlike some of the universal fans out there, the blades on our fans are easily reversible, not just the motor. This means you get the superior flow of a curved-blade design with the versatility of a push/pull reversible fan.
  • Unlike some of the universal fans out there, our fans include the mounting feet and ALSO come with through-radiator mounting kits that sell for $5-$7 at most auto parts stores.
  • Unlike some of the universal fans out there, our fans are only 2.5" deep at the deepest point, making them ideal for installations in cramped areas.
The Radiator

These multipurpose radiators are designed to cool fluids in a wide variety of circumstances.

  • Two inches thick, they cool fluid as close to ambient temperature as possible and are easy to mount in tight locations.
  • With four strategically placed mounting points, they are easily mountable with the water inlet and outlet on either the top, bottom, left or right.
  • All aluminum construction provides maximum cooling.
  • Recommended for up to 120 PSI, they are perfect for just about any automotive heat exchanger application.
  • A special feature that is only included with these Shaman Equipment radiators is a customizable inlet and outlet style. The fluid inlet and outlet are 1/2" NPT female threads, just like most air to water intercoolers. This item also ships with two adaptors that can easily convert the inlet and outlet to 12 AN.

A perfect match for the intercooler core in every way.

The Pump

The pump is the key to producing such an economical kit. Other pumps which are purpose built for water to air intercooler systems cost up to ten times as much!

These Rule 401FC pumps are designed for livewell/baitwell/bilge applications but their high flow rate and low cost makes them ideal for use as water to air intercooler pumps.

  • Must be mounted at the low point in the system - these pumps push water but they will not pull it.
  • Must be mounted after the water in your system is cooled (after radiator or icebox) - excessive heat may result in premature pump failure.
  • Pump operates on 12V-14V DC.
  • Flow rate: 500 GPH.
  • Designed for use with room temperature water, however we have tested these pumps long term with 130 antifreeze/coolant with excellent results.
  • Designed with a minimum 1500-hour service life in mind, these pumps come with a 3 year warranty direct from Rule/ITT. However, use with high temperature water and/or antifreeze/coolant may void this warranty.

Pump is brand new and will be shipped in retail packaging.
