We do those often, another just today SO I'll be nice and give you a tip BEFORE you try tearing into it. There's a TSB on this proceedure which mentions the kit with all the hose clamps, seal and intake gasket and you NEED a special tool to loosen ONE bolt. The bolt on the left side of that breather box needs the tool which is an offset 10mm wrench/socket extension and it's needed because the main bracket that holds all the driven accesories (alt, PS pump, AC comp) is in the way and you can't get a normal socket on it.

I'm telling you this so you don't try this before knowing as otherwise you'll be saying several bad words. You can either order that special wrench through a dealer, pay them to do the job or try your luck improvising?
