I've recently made several maintenance book stickers for a 997 TT owner.

I'm not sure but Porsche discontinued the underhood sticker codes through 2006-2007 though they keep using the maintenance book one.


Some people like to get a copy in the underhood place (as former Porsche series), so I did the reproduction. Other people missed the maintenance book and had to ask for a Duplicate (comes blank) and prefer a good reproduction instead of the Porsche dealer's hand writing. I show you the stickers finished:

(I did for 911 SC, 3.2, 964, 993, 996 Mk1, 996 Mk2, but they are the first I made for a 997)
