Krank Vents System

The patented Krank Vent System is designed to relieve crank case pressure and produce a vacuum in the crank case of any engine.
This helps your engine operate more efficiently, helps seal piston rings better and reduce blow-by, and reduce or eliminate smoking.
NOTE: When installing this you will also want to replace the PCV valve with a straight-through hose fitting: PCV Replacement Fitting.
