To maximize filter performance, Moroso race oil filters have a filtration rating of 27 microns. This results in a maximum pressure drop of only 2.5 psi, which results in more flow, less oil bypass, and maximum filtration performance, which is so important in severe racing conditions. Made with roll-formed threads for a precise, tight fit, and with an anti-drainback valve to keep oil in the filter after engine shutdown, they are perfect for any race application.

When roller rocker arms are installed, along with a mechanical lifter cam, the amount of oil flow required to the valvetrain is greatly reduced. Installing Moroso oil restrictor kits limits this unnecessary oil flow. These kits reduce the power-robbing windage created from the excess oil draining past the rotating assembly and keeps the oil flowing where it is needed most, the rod and main bearings.
