Thermostatic Oil Filter Sandwich Plate

This Thermostatic Oil Filter Sandwich Plate installs between the engine and oil filter, providing thermostatically controlled connections for an external oil cooler. Its straight hose connection layout suits installations where there is sufficient clearance around the oil filter mounting area.

Thermostatic Oil Cooler Control

The built-in thermostat begins opening at the selected temperature and progressively directs oil through the external oil cooler circuit as oil temperature rises. Continuous bypass flow maintains circulation during warm-up.

Replaceable Thermostat

Choose from 82°C (180°F), 92°C (198°F) or 102°C (216°F). The installed thermostat can be replaced with the same temperature or changed to another available temperature if required.

Oil Filter Thread Options

Choose between M20 x 1.50 and 3/4"-16 UNF centre bolt threads to suit the engine's original oil filter mounting thread and compatible oil filter.

Optional AN Hose Adapters

Two M22 x 1.50 female hose connections can be used directly or supplied with two AN6, AN8, AN10 or AN12 male adapters.

CNC-Machined Aluminium Construction

Manufactured in the UK from 6082-T6 aluminium with a grey anodised finish, the sandwich plate includes a nitrile O-ring and is suitable for oil-filter sealing diameters from 52–75mm (2.04–2.95").
