When building a Subaru race car, the OEM thermostat housing is often an overlooked restriction in the cooling system. The stock housing relies on rubber hoses and standard worm-drive clamps, which can limit coolant flow and require tools for removal—less than ideal for high-performance or track-focused builds.
The IAG "Wiggins" Style Thermostat Housing replaces the OEM unit and uses a specialized Wiggins clamp, providing a flexible, tool-free connection. This housing improves coolant flow over the OEM design, enhancing cooling efficiency during high-stress applications.
Features:
- Outflows restrictive OEM thermostat housing for improved cooling
- Wiggins clamp connection allows easy installation and removal without tools
- Lightweight and strong design ideal for race, rally, or track applications
- Proven technology used across motorsport, aerospace, marine, and industrial applications
- Saves assembly time while providing flexibility and durability
Note: Custom fabrication is required for the lower radiator hose assembly. (-24 Wiggins clamp not included)
