Could someone post the exact OEM part number for spark plugs for 2007 997.1 C4S? Porsche branded costs $120 but I'm sure OEM BOSCH would be less.

Thanks

Thanks, did you get Bosch or NGK? and how much did you pay for labor?

OEM Bosch, along with the OEM Beru coils. I did the labor myself, fortunately while I was doing Fabspeed exhaust, waterpump, belt & pulleys, and Wevo engine mounts. With the whole rear of the car disassembled, it was a breeze. With mufflers in place, you may have to be a contortionist in order to reach the T40 bolts on the rear most coil on passenger side.
