Its all in how you approach it.
You can go bare bones and simply unbolt the air pump lines from the block, and install the plates.
The real headaches come from removing the actual system itself.
The biggest problem being the line that runs from the passenger side valve to the passenger side. It is underneath the intake manifold and the line for it is hurried under everything on top of the block.
The drivers side is cake, it comes out in one piece in under 10 mins.
Also make sure if your car is an 07 to remove the multi pin (can't remember how many 8-10) connector from the top of the valve and re connect it.
That's the atmospheric pressure sensor.
If you have any other questions ask away.
