There are a couple schools of thought on the bags- you can buy them and do the install yourself, or have the dealer do them and in the process set the "Z" height adjustment and do the code update for the sensors & compressor cycle.

I would rather have done them myself, but had the dealer do it since I needed the code update anyway.

If you have an 03 there is an update so the compressor won't cycle so much, ask them to also update the "auto volume" on the radio at the same time. Early versions of the code didn't time the signal to the sub at the right time so the auto volume button has to be cycled each time after the system is on, unless you do the update.
