Nothing fancy. Just make sure you unhook the MAF plugs before you start pulling on the Airbox too hard, the cable/wires are fairly short and you can only lift the Airbox slightly before you come to the end of the slack. While your there take a good look at all of your Vacuum hoses, you may want to replace a few of them while your in there. I just replaced my MAF Seals a few years back and I also lubricated the Seals with 100% Dow Corning Silicone grease (111) and it helps the MAF's slide in and out easier as well as making a better seal.
Thanks for the info
