A Moroso oil restrictor kit for Chevrolet big- and small-block engines, supplied as a two-pack with a .0625-inch orifice. It controls internal oil flow where tighter metering is required, helping tune oil pressure for modified valvetrain or pump setups. Handy as a direct replacement or for engines that need precise metering without fabricating custom restrictors.
