When you put a BOV on IC piping you get rid of bothe valves going to the intake box right? What vacume line do you use for the new BOV? What do you do with the extra Vacume line from the second valve you take off??

 

Leave the rear valve alone. It's the CRV... You need it if you are sequential. You CAN remove the hoses from the intake box... That just vent's them and makes them louder.



If you are replacing the stock BOV to one on the IC piping... Remove the stock BOV completely. Plug the large hole on the Y-pipe. Follow the vacuum line to it's source. Remove it and replace it with a new one that will reach the new BOV in it's new location! You're done!
