These OPEL direct injectors are about 13% larger than the stock LNF injectors and they have an improved "e85 compliant" injector seal. They are also extremely delicate so they will come pre-installed in a specific fuel rail to decrease the chance of damaging the injector and for an easier install. The injectors should not be removed, and will not work properly in a stock LNF fuel rail.

The stock LNF injectors are 120#, and the Opel injectors are 135# per hr at 10 mpa.
Comes without a pressure sensor, you can reuse your stock one.
