DIY: Finally Installed The STILLEN G3 Intake today! Lots of Pics inside (AK370Z)

Trips

If you don't have a spare piece of hose laying around?

Head to over to a nearest auto parts store and buy a small piece and slice it down the middle and wrap the AC line.

It should look like this

It looks like in your picture that you only cut one side of the intake hole to make it bigger. Before i go all Chainsaw Massacre on my car I wanted to make sure I had this down.
A couple of questions:
-Would cutting the hole on the bigger side be better (lots of room for the intake), or do you want this hole to be a snug fit? (I think I saw that if it was tight you would get noise?)
-Is it best to just cut on the inside of the intake hole as you did in the pic, or should I trim both sides?

Thanks for your help,
