KRANK VENT RELIEF VALVE PLUS

More than simply venting your crankcase fumes, the Krank Vent Plus controls the air under the pistons by maintaining the proper amount of vacuum in the crankcase at any RPM.

You'll gain 2-8% of useable rear wheel horsepower. Your engine gains a quicker throttle response.

The unit snaps open for easy cleaning, is not restricted to position and is compact and light weight to fit all Harley Davidsons, including the hard to fit 93-up head-breathers.

• Installs on your crankcase breather hose.

• Controls the air under the pistons by maintaining the proper amount of vacuum in the crankcase at any rpm.

• Better seal is achieved due to an increased pressure differential across the compression ring.

• Designed to give a 2-7 horsepower increase, with a deeper motor sound.
