Hey guys, just a general enquiry here about installing a pod filter. Now I'm totally aware that being an 8v I'm not going to get any gains whatsoever with a pod, and that it's actually pretty ricey and stupid to put one on (just want it for the sounds lol) but my main question here is, how do I go about the install?

I'm aware that my MAF is on the top of my intake manifold? pic:



but if you take the panel filter out and look underneath, at the bottom of the airbox there is a tube from the exhaust coming into the airbox? Could this be to do with cold starts? Does the orange braided cable control the little valve?





I've been searching for a few days to find an answer somewhere online but it I'm having no luck.

Cheers.
