Air to Water Intercooler Core Type 21, Supports 2000HP

Air to Water Intercooler Core Type 21, Supports 2000HP



Water to Air Intercooler, 17"x12.25"x9", O/S I/O (Type 21)

This is an enormous water to air intercooler.

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 nine inches. Recommended for up to two thousand horsepower.

100% Lightweight aluminum, No Epoxy Used In Core

Recommended for up to 2500 CFM / 2000 HP
Pressure Drop: Less than 0.5 PSI. This is not a typo! Liquid/Air Intercoolers have incredibly low pressure drop.
Inlet: 4" Outlet: 4"
Maximum water/air pressure: 70 PSI
This intercooler has the inlet and outlet on the OPPOSITE SIDE.
Core Size: 9.5"x9"x9" (Endtanks add to length)
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!

10% Restocking Fee Applies to ALL returned Air-Water Intercoolers.
