Tomei Oil Galley Orifice for RB26DETT (TB2040-NS05A)

The oil galley orifice controls the oil flow to lubricate parts in the cylinder head and to cool the engine assembly. The stock orifice has a large 2mm hole which can allow too much oil and cause problems. By restricting the diameter of the orifice to 1.5mm, you will receive enough lubrication to the cams and valves while maintaining the correct amount of oil in the pan which resolves common problems.
