Frozenboost Water to Air Intercooler, 150PSI 20.25×15.5×12 S/S I/O


Available on backorder


This Liquid/Air intercooler is built for massive boost. Special innovations in the core and end tanks allow it to operate at continuous pressure of over 150 PSI.

Each of these intercoolers is pressure tested to hold 170 PSI for 30 minutes at the end of production. The trade off is that a slightly thicker metal is used in the intercooler, reducing efficiency.

The proportions are somewhat ridiculous, please make sure it will fit before ordering. If you have the room, there’s nothing better.

The height, its smallest dimension, is twelve inches. This intercooler is more than thirteen times larger than our smallest core. Recommended for up to three thousand horsepower.

100% Lightweight aluminum, No Epoxy Used In Core

Fin pitch is 17 fins/inch – 8.5 air side and 8.5 water side.

Recommended for up to 3800 CFM / 3000 HP
Pressure Drop: Less than .8 PSI. This is not a typo! Liquid/Air Intercoolers have incredibly low pressure drop.
Inlet: 4.5″ Outlet: 4.5″
Maximum water/air pressure: 150 PSI
Core Size: 12″x12″x10″ (Endtanks add to length)
150 PSI Water to Air Intercooler The inlet and outlet on this intercooler are 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.


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

A liquid to air intercooler setup requires several components, including the core, a water pump, a heat exchanger (radiator), and an optional reservoir. We carry all of the parts you need.
