Hey there,

I’ve recently brought a 2006 WRX and am about to start modifying it.

one of the things I wanna get done first is a boost gauge (because why not). I was just wondering where I should get my vacuum source from? 
I’ve done a bit of research and come up with everyone just going off the BPV/BOV Hose but I’m a little sceptical?

should I just go off there or is there a better location?

if you can help that’ll be great, and if there’s any chance of pictures that would be amazing!!!!

Thanks in advance for the help!!

Take a look in the how to & faq's 

The best place is to tap into the vac line coming from the manifold, i'm not too familiar with the new age cars but a google should help you 

Stants is spot on, my 04 wrx has been installed by previous owner by a t piece at the manifold right next to the alternator (red cap)
