    Moroso 22016 - Moroso Oil Restrictors Details

    Theses Oil Restrictor Kits reduce the oil flow to the upper engine assembly, leaving more oil available for the rod and main bearings. Reduces power-robbing windage by reducing the volume of oil passing by the rotating assembly on its return to the pan. Not for use with hydraulic roller or flat tappet camshafts.


    Orifice Size (in.)
    Sold as a pair
    Thread Size (in.)
    1/4 NPT
    Manufacturer's Part Number:

    Moroso oil restrictor kits limit the flow of oil to the rocker arm assemblies, leaving a greater percentage of oil for the rod and main bearings. And less oil in the top end of the engine means less oil that has to pass by the reciprocating assembly on its way back to the oil pan.

  • Reduces oil flow to upper engine assembly
  • Reduces power-robbing windage

    Note: Do not use with hydraulic lifters.
