This is useful when converting a 1.6 to have a thermostatic oil cooler as the line connections can foul the block. The Mocal Sandwich Plate Spacer is made from billet aluminum. This spacer can be used with both Mocal sandwich plates, thermostatic (M-OTSP-1) and non-thermostatic (M-SP-1) types. Measures 80mm in diameter and 25mm deep. Uses an 'O' ring to seal against the mating face. This will require a longer than normal extension bolt, this is a separate item.
