1. yes.

2. yes. if you still have the catalytic converters, removing the air pump is bad, the converters need to be removed first. you also should remove the Air Control Valve (ACV), its the thing the air pump pumps into, and install a block off plate.

3. a 12mm socket wrench. 10mm socket to remove the ACV

Search thread titles for "emissions removal" or terms to that effect.

An S4 NA can ditch the air pump if you're also removing the cats and other emissions related components. But when the air pump is removed, the water pump pulley will be able to slip due to lack of belt contact. There are 2 solutions: a double sheave alternator pulley, or a "yoohoo" belt, which goes around the main pulley and water pump pulley.
