Replace a worn out or old rear oil passage plug with Moroso oil galley barbell plugs. Your vehicle's old plug could be allowing dirty engine oil to bypass the oil filter. Moroso's improved design features a secondary O-ring to seal dirty oil from flowing to the engine bearings. These dog bones also have a smaller shaft diameter than the OEM piece to minimize any flow restriction. Moroso's oil galley diverters are machined from billet aluminum, not plastic like the original OE piece, and are supplied with quality, high-temperature rated Viton® O-rings to withstand all types of engine oils and compression cycles. Whether you call them passage plugs, dog bones, or barbells, these Moroso components can be easily removed from the engine block once installed with its 4mm threaded hole.

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.
