FYI, it's not a cooling unit - the design runs hot coolant through the throttle body to prevent icing. If you live in a mild climate where near-freezing temps are not an issue, you can usually bypass the coolant loop in the throttle body with no issues, and it actually might gain you 1 or 2 hp due to the cooler intake air.
