Description

Top Street Performance water necks are designed to help to hold the vehicle's thermostat in place as it opens and closes—to regulate the flow of coolant through your engine. The opening in the water neck created by the thermostat allows coolant to flow from the radiator back to the engine. Composed of high-quality aluminum, these water necks are available for multiple applications in both polished and black finishes and include bolt hardware for installation. Order the model designed for your application.
