Most classic Mini oil pumps available today have the same basic design, but modern factories in their quest for production volume have sacrificed precision. This pump is CNC machined from alloy billets with sintered internal components, assembled to very exacting standards. These close-tolerance pumps produce consistently high oil pressure even at any RPM. There is less oil drag on the pump giving potential for higher HP. Sold each.
