They should fit, ID has our car in the specific fitment charts.

The part number you're after is 1050.11.03.60.11.2

ID's part numbers are pretty well structured actually, the numbers all denote something, like bore size the o-rings are meant for, etc.

The part number for my ID720s (720.11.03.60.11.2) are exactly the same except the first number.

I foresee no issues running ID's new X series injectors. My older gen 720s sit deep inside the fuel rail, the fuel rail touches (or almost, can't remember) the bulb part of the top adapter.

Looking at the dimensional drawings, the new X series injectors are shorter by about 5mm, bringing the distance between the inner sides of the O-rings to 60.1mm vs 64.7mm on the previous gen. Which explains the use of the spring on the top adapter of the injector.

In comparison to the stock EV1 style injectors; the distance between the inner sides of the O-rings are actually 59.7mm

Good luck!
