Water Temperature Tuning
These Be Cool water speed restrictor plates allow you to control the coolant flow leaving the engine. By slowing down the flow of water, you control the amount of heat that is absorbed by the coolant. The plates have a 5/8'', 3/4'', and 1'' hole for flow tuning. Kit includes plates for GM, Ford and Mopar applications with large or small thermostat housing.
