Prolonged use of an engine in conditions where the oil cannot reach its correct working temperature will cause sludge formation and crankcase oil dilution, leading to excessive wear especially in the cylinder bores. The elimination of drag in engines caused by cold oil is a most important consideration, especially with a racing engine, revving the engine without a load will not put much heat into the oil and devices for preheating the oil may not be available. Optimum engine power will only be delivered at correct temperatures. It is therefore desirable to control of the oil flow through the oil cooler kit by a thermostatic device is set to divert oil to the cooler at 82ºC. Comes with:

• It is a straight bolt-on design to be use with an -10AN Oil cooler kit.
• It comes with 2 different oil housing center fitting, M20 & 3/4-16UNF.
• 2 X 1/8 NPT side ports for oil temp/pressure sensor insert
