I just got a used Injen Short ram Intake (sounds awsome)

the vacume hose is just the right size but there is no slack whatsoever

Where can i get hose for it and what size hose is it ?
i looked at pepboys and homedepot

 

before bed bump...

 

where else but a hardware store?

 

have you tried your local autoparts store? you should probably look there first as i'm sure they carry plenty of vacuum hoses.
