Wehrs - Radiator Restictor

Aluminum Radiator Hose Restrictor

This restrictor installs in the lower radiator hose, replacing the thermostat to slow water flow and keep coolant in the radiator longer. By increasing cooling time, it ensures the water is cooler when it reaches the engine. Machined from durable aluminum, it’s designed for use with aluminum racing radiators.

• Replaces thermostat in the lower radiator hose
• Slows water flow to improve cooling efficiency
• Machined aluminum construction for durability
• Optimized for aluminum racing radiators
