Speed’s Crank Vents

Speed’s now introduces their own line of custom crank vents, manufactured by ET performance. These crank vents are available at an event near you, installed while you wait by the Speed’s Performance Plus team. Speed’s is also offering these crank vents for sale online.

This crank vent is different then any other vent. It has a longer stem to allow the proper room for most air cleaners. The vent itself has a patented valve that doesn’t use check-balls, springs, flapper, or umbrella valves that quickly fail, and only allows one way flow. The vent takes the blow-by out of the heads or crankcase depending on the year of bike, and sucks it out through the vent.

This allows for all that pressure to be released from the motor and let the motor to run cooler and more efficient. It will help increase gas mileage, increase horsepower, and increase the life of your motor. This crank vent falls under US Patent No. 5967178.

By relieving all the pressure it will help to increase the life of all your gaskets in your motor as well. They come in polished aluminum only. If braided hose is needed we furnish that as well.

We have crank vents for all different engines for installation on your bike now. Please contact Molly, 763-241-0537, for more information about applications and pricing, or see the 2007 Dennis Kirk catalog, or Drag Specialties.
