JEGS crankcase evacuation kit is designed to alleviate the pressure that builds in the engine due to the windage created from the rotation and speed of the internal components. Increases the performance and durability of your engine by aiding the seal of the piston rings and reducing the tendency to create oil leaks by pushing out gaskets or contaminate the intake charge due to excessive blow by. Not for use with mufflers.

Kit includes two each of the following: chrome plated ''JEGS'' embossed push-in style breathers, 1.25'' grommets, one-way check valves and weld-in tubes for the collectors. Designed to utilize 5/8'' or #10 tubing (sold separately) to connect the breathers to the check valves.
