Water-to-Air Intercooler System Components

Instead of relying on cooling airflow, an air-to-water cooler uses coolant to pull heat away from your forced-induction intake air charge. No airflow required means you can stuff the intercooler anywhere you have room. That lets you keep the intake hose undes shorter. It also means less heat soak when the vehicle sits between runs. But you can't just tap into your engine cooling system and get good results! An air-to-water intercooler requires its own full cooling system including a coolant reservoir, circulating pump, and a radiator (water-to-air heat exchanger).
