Okay so with many pm's asking how to install these grilles I decided to go out today and do the process agian with pics so fellow members can see how easy this is to do. All you need is a Torx-20 screwdriver and about 20 minutes.
First off remove rubber strip in the center on the hood right in front of inside bumber.
Once done you should see two hex bolts underneath.
Now you can start removing the 6 hex bolts using the Torx-20 screwdriver. The 2 in the center is straight forward but the two right on top of each headlight has a cover the needs to be removed first.
There's two clips/locks holding the cover in place. All you need to do is with you fingers just pull the center pin up ( real easy )
Below. Repeat on other side
Once all screws are removed you'll need to pull the center of the front bumper forward to remove chrome grilles. There's nine clips holding it to the bumper. With one hand just pull the grill out on the portion of the grill where you are pushing the clip down with your other hand.
Once both grilles are removed you'll see this.
Now time to install BMW Performance Grilles.
Side by side comparison.
Time to put everything back. The two hex bolts on top of the headlights need to be put on first before the clips/lock pins.
Then place the clip/lock pin in and press down then put lock pin in to secure.
The center piece removed in the beginning need to snap back in.
Now the extra....... Painting silver trim near the fog lights.
All you have to do to remove the mesh is take two fingers and pull forward on each corner to remove the mesh.
Unclip the three parts holding the trim to the mesh.
Paint trim with matte black or gloss spray paint. Your choice. I used matte black then reverse process and install.
Here's the completed look.
Hope this helps all the DIY'er.
