Intercooler-Charge Air Cooler

Find New OEM intercoolers and charge air coolers for turbocharged GM vehicles. Our factory-original intercooler cores and assemblies are sourced from GM surplus — the correct core size, end tank volume, and pressure drop characteristics for the Cadillac ATS-V, CTS-V, and other turbocharged GM applications.

The intercooler reduces charge air temperature between the turbocharger and engine — increasing air density and preventing detonation under boost. OEM intercoolers provide the factory-specified pressure drop and heat transfer capacity that the engine's boost control strategy was calibrated around.

Intercooler replacement requires boost system pressure testing after installation. Verify part numbers against your vehicle's engine and boost system configuration before ordering.
