If you have the stock rubber inlet tube, I always just unhooked the top from the airbox and then loosened the clamp on the TB and took moved the inlet tube and airbox top out of the way. You will also need to unhook the electrical connection at the MAF and the clamp on the tube that goes over to the driver's side valve cover. No seals are needed for replacement.
If you are trying to get the aluminum upper IC tube off and out of the way, then it is a little more involved and you will need some type of sealant, either the stock thick teflon tape or sensor safe RTV sealant.
