Evac filter 1.5" ID. 3" tall x 3" wide.
With this Evac System you have no more use for a catch can on your jr dragster! This Evac is mounted to the head of the motor and runs oil right back into the block, releasing crank case pressure. With this special design, you can use your rags for something more useful than wrapping them around your air filter. That's right, NO BLOW BY!!! (Breather shown in mounted picture is NOT included. Breather Shown in kit pictures Included.)
