Just need to know what size filter to order off eBay to ditch the IAC plumbing from my intake. The hose is starting to crack so I'm just going to cap/filter the bitch. Search turned up nothing and I only have one car down here so yanking it off and taking it in to NAPA is hard/impossible.

 

Why not just measure it?

 

I'd worry about boost going the wrong way out the IAC valve if it wasn't attached to your IC plumbing.
