Feuling billet aluminum dipsticks vent/breathe excessive crank case pressure from the oil tank through a PVC style breather consisting of an oil separator system, perforated disc, replaceable filter element and umbrella flapper valve. Feuling vented dipsticks screw into the factory oil fill spout as a stock replacement part. These breathing dipsticks remove unwanted build-up of blow by pressure in the oil tank.
Blow by is pressure that is forced past the rings & cylinders, pushed into the crankcase & then forced back into the oil tank. Feuling dipsticks help remove this unwanted pressure through a Crankcase Ventilation System (CVS). Test results show a decrease in engine oil sump levels, more freely/smoother revving engine, increased MPG & decreased blow by.
WE INCLUDE 2 VENTING OPTIONS TO CHOOSE FROM WHEN INSTALLING OUR DIPSTICK.
