me and a friend just did both our 3.0's filters (his is 02, mine 03) on Saturday. Took less than an hour to do both from getting the first car on ramps to getting the 2nd car off the ramps. We both have the 1 inlet/1 outlet type, and it was pretty simple. The only thing that took a couple minutes to figure out was the inlet clip- the little tab you have to push is the same color as the clip, all black. While the tab on the outlet is white/clear. Once we saw that, then we were able to locate the same tab on the inlet.

anyway, thanks to the OP for this DIY, made it really easy!
