We have reproduced the factory competition part 11G176 so that your car can now benefit from years of factory competition experience. For sustained maximum power and speed, such as racing conditions, it is advantageous to remove the thermostat to ensure maximum water flow, but only when this thermostat bypass blanking sleeve is fitted. By merely removing the thermostat, some uncooled water will go through the bypass. This sleeve minimizes this to provide maximum cooling.
