I've gotten mine done for $120 parts and labor, $112 in parts $8 in labor at my local Porsche mechanic.
Great guy! Uses mobile 1 full synth and oem filter. Can't beat that, maybe that's how he keeps me coming back for everything else I need done to the Box.
Some people just know how to do business and keep it.

Around $2-250 at KC dealer. I do it myself in an hour for under $80. Less time than it would take to coordinate with a dealer, the the trip there, then back etc... Plus I like doing it. I take my newer domestic vehicles to the dealership for even the most basic things. I don't want to mess with them and it's not as fun as working on the Boxster!
