I too am investigating this subject but am hesitating for lack of much discussion of this subject -so thanks BY.
Please correct me but I understand the upgrade injector is a Bosh Gen 3 ,part # 0280155890. The Porsche # is 996 606 120 00 ? This is a '4 hole' injector.
My originals work fine but as part of my engine rebuild I need either a repair kit or the upgraded injectors. The repair/service kit is $25 for all 6.If I send my originals out for service +flow test it is $300+. The 6 new,upgraded Bosch injectors are $315.
Check your injectors before you buy -if they are a dirty beige color and have "0280 156 053" on the side, they are 4 hole, Gen 3.The problem is you have to remove one injector to read this number.
