About X-code codes
X-codes are Porsche Exclusive / Tequipment-style factory personalisation options, typically fitted by the Exclusive department at Zuffenhausen. On a 996 you will usually find X51 on the option sticker in the service/maintenance booklet, the front-trunk data label, or the original window sticker (Monroney label in the US).
Confidence “high”: meaning confirmed by at least two independent public sources. Option meanings can differ between markets and model years.
