9.5x9x9 Intercooler 4-Inch NPT

Constructed entirely from lightweight aluminum, it avoids the use of epoxy in its core, ensuring durability and optimal heat transfer. Featuring a fin pitch of 21 fins per inch, this intercooler is engineered with specific densities for both air and water flow (12.5 fins per inch for air and 8.5 fins per inch for water). This design contributes to its remarkable efficiency. It is recommended for systems generating up to 2500 CFM or 2000 horsepower, with an impressively low pressure drop of under 0.5 PSI. The core dimensions measure 9.5"x9"x9", and it includes 4" NPT inlet and outlet connections. This unit is rated to handle a maximum water/air pressure of 70 PSI. It's important to note that both the water inlet and outlet are located on the same side of the intercooler, and unlike many other intercoolers, it utilizes NPT threads for easier fitting availability in the United States. Frozen Boost emphasizes that this is a genuine water to air intercooler core, where water passages are significantly smaller than air passages, contributing to its compact size and low pressure drop. This contrasts with some products that use an air-to-air core design, leading to reduced efficiency. A complete liquid to air intercooler setup requires additional components such as a water pump, heat exchanger, and potentially a reservoir, all of which are available from Frozen Boost.
