It comes with the emblem lots grill, and 2 filler pieces for the hood, the bumper and a small tube of glue.
To change the grill must be removed only 2 screws and then the detents above (easily accessible, just push in through the long holes with a screwdriver while gently pulling the top of the grill [from one to another page).
Downstairs there is a bit more difficult to release the locking, either you go (look at the new grill, where there are the catches) or pull gently but firmly to a mounting wedge between grill and bumper.
If you've made this, simply use the new grill and screw and you're done.
Now of course you have upper and previously filled by the emblem beneath the grill "quencher".
The filler pieces shipped with I brought to the painter and paint to corresponding color code of my car and can also be glue.
The Entprodukt for me is acceptable (price / performance), it would be nice of course, when the extinguisher fully closes and then this completely repainted in hood and bumper, because we see just the joints.
