Part of the AGA Clean Oil Series, the Crankcase Vacuum Regulator Ford Kit is designed to crate a vacuum inside the engine. This vacuum is just enough to hold the oil back, allowing the user to swap out drain plugs, oil level sensors and such.
With a built in regulator, only allowing about 1" of vacuum, this will ensure there is no damages to the engine components.
The kit includes the regulator, 37mm adapter and 34mm adapter, covering many of the Ford model lineup.
