Billet Aluminium Oil Thermostat




4 x -10 ORB ports, 1/8" NPT Port

Perfect for use with Aeroflow oil coolers, this Billet Aluminium thermostat helps maintain engine oil temperature by holding the oil until it reaches operating temperature at (82°C) 180°F when the thermostat is fully open to allow full flow to the oil cooler. It will self-adjust flow according to the oil temperature to maintain a constant operating oil temperature just like a coolant thermostat would operate.

The main body is made from billet 6061 aluminium, then anodised black for great looks and corrosion resistance. This features four labelled inlets and outlets -10AN ORB ports provided for plumbing the engine oil to and from the sandwich adapter and the oil cooler. Two 1/8" NPT ports and plugs are provided for auxiliary sensors.

To run this product correctly a sandwich plate adapter or block head adaptor must be installed onto engine to allow the lines to run to the external oil cooler. Use Aeroflow Performance products such as AF64-2108 oil cooler sandwich plate, AF64-2060 sandwich adapter.
