PCV tube, there's 3 total and that is the passenger side one, I like the green electrical tape.

You can buy just that hose, but I can tell the other ones aren't far from failing so you should buy all three. Also, where's your battery cover?

 

Not to hi-jack your thread, but anyone know what this rubber grommet to the battery compartment is called or where I can find one? Might just have to make a trip to the junkyard

 

Aside from going to a wrecking yard and looking around for one your best bet is probably buying a generic kit off amazon or something, just use the keyword "rubber grommet kit" but you're probably only going to find ROUND grommets, it will work though, the battery compartment cover will squish it down enough and you can trim it if needed.

 

Actually I have a couple local LKQ junkyards that are pretty organized. You search for the car you need and it tells you what aisle and row the car is in. They always have a few g35s. They just get picked apart so quickly

 

I can't imagine that is a high demand part....
