About UPI Thermostat
The Inferno thermostat bypass valve (for 1″ radiator hose) provides a more consistent heat. More coolant will be directed through the heater before it is passed to the radiator.
Our thermostat bypass valve allows you to achieve quicker heat – instead of waiting for the engines thermostat to open up you can bypass the coolant with this valve so you can achieve optimal heat, quicker!
