This used BMW genuine OEM Turbocharger Intercooler (part number 7846235) replaces 4802574. As a turbo intercooler, it cools compressed air from the turbocharger before it enters the engine, ensuring denser, oxygen-rich intake charge. When failing, common symptoms include reduced power, increased intake air temperatures, and heat soak during hard driving. This intercooler mounts between the turbo and throttle body, directly affecting performance on the 3.0L turbocharged inline-six.
