Coolant Flow Restictor
[Z16580]

Coolant Flow Restictor
$11.25

This billet aluminum restrictor from Northern replaces the factory thermostat on race engines to slow the flow of coolant from the engine to the radiator.

By slowing the speed of the colant, you enable it to absorb more heat from the engine and also allow it more time to dissipate in the radiator.

The restrictor is CNcC machined with a specially designed radius to prevent aeration and creates better flow.
