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

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.
