Part Number: 21-307

KRANK VENT PLUS - Part Number 21-307
More than simply venting your crankcase fumes, the Krank Vent Plus, when installed on your engine breather hose, controls the air under the pistons by maintaining the proper amount of vacuum in the crankcase at any RPM. This prevents the engine from working against itself and prevents blown or weeping gaskets. You'll gain an added benefit of 2 to 7% increase in usable rear wheel horsepower. A better seal is achieved due to an increased pressure differential across the compression rings. The engine sounds deeper and is more powerful with a quicker throttle response. The unit also snaps open for easy cleaning.
