You guys have discovered what I discovered years ago-- it's difficult to find things in the Hyundai manuals. I'm much better at it now that I'm accustomed to the "Korean" thinking and organization system.
I looked in the shop manual for a 2002 Sonata (EF) 2.7 V6. In the engine mechanical section, go to "intake and exhaust," "intake manifold," and "removal." Still, you'll need to do some of your own analysis, as you won't need to remove the entire intake manifold, just the intake plenum.
On the other hand, in the 2000 Sonata (EF) 2.5 V6 Manual, you can go to the "Surge Tank" section after choosing "intake and exhaust," and there's a section for removing the surge tank alone. The engine is externally the same as the 2.7, so these instruction should also apply for the 2002.
