Water Neck Spacer - Black

The Water Neck Spacer - Black by MEZIERE is an essential component for engine builders and performance enthusiasts seeking to enhance thermostat housing positioning. This compact adapter acts as a bridge between the engine block and water distribution system, enabling customization of coolant flow geometry without extensive modifications. It's particularly beneficial for those running custom intake manifolds or upgrading to electric water pump setups.

Constructed from durable black-anodized aluminum, the Water Neck Spacer is designed to resist corrosion in both coolant and ambient environments while providing rigid support. Its precision-machined design ensures proper alignment with the water pump inlet and thermostat housing, optimizing circulation efficiency. The spacer is engineered to maintain proper gasket sealing surfaces and thread engagement, accommodating flexible mounting angles.

Ideal for engine swaps and custom engine bay layouts, this Water Neck Spacer addresses alignment and clearance issues that stock configurations may not resolve. It is particularly useful in builds where factory water neck positioning creates interference or flow restrictions. Mechanics and fabricators will find this spacer invaluable for high-performance cooling circuits in both street performance and racing applications.
