What you want are Bosch Twin 582S.
That will include the driver side wiper you want (with the integrated wing) as well as passenger side blade that has a curve that follows the base of the windscreen.
Not sure you can get the driver side separately.
I also see the Porsche part number for the set on my receipt as: 996 628 901 08.
Ok, I just checked the PET to verify that part number and it doesn't show them sold separately, only as a set.
Here's the best price I could find on ebay:
2-pcs Front Wiper Blade 22" Bosch 996 628 901 08 Porsche 996 997 986 987 911 | eBay
Be careful - you want genuine Bosch blades because aftermarket/compatible blades will be missing the wing on the driver side and the passenger side will be straight (not curved).
