How to fit an RS6 Grille on a B7 A4, S4 or RS4 (All Mesh – No Filler Plate)

This is a REALLY cool mod submitted to me by a reader and all-around cool guy Richard Edwards (aka BigRich). He did this on his car and was nice enough to write-up the process and share it with us. This should work on any B7 including the non-s-line version, but is pictured above in the S-line/S4 bumper.

First, you need to buy an RS6 Grille. They’re not cheap, especially here in the US, but not too much more than an RS4 grille either. The best prices for these seem to be eBay, and you can view the most recent listings below:

Next you need to cut the RS6 grille away from the surround. I used a small hack saw blade and taped it up with some insulation/electricians tape so I didn’t go cutting myself! Alternatively, a Dremel would work nicely to cut the mesh out quickly & easily, just be sure to make clean, straight cuts.

Once complete, you should have a large sheet of mesh, as pictured above.

Once you’ve removed the grill from the surround, you need to do the exact same with your A4/S4 grill, its recommended you purchase a spare grill to do this to in case you mess up and need to refit you old one.

When you’ve got them seperated, start to marry them together. You might want to take the chrome surround piece out of the grille (but leave the rest of the backing in place) to make sure it doesn’t get scratched. You’ll need to trim the edges of the RS6 grille but this is trial and error so be careful. The RS6 grill is bigger but only by a bit around the edges, so you’ll have to trim quite a bit from the bottom as the RS6 grill as it has a deeper bottom to it than the A4/S4, but again its trial and error so still be careful.

Once you feel it looks good and fits tight………Glue it, yes that right glue it! I used super glue to get most of the edges started and then once it felt good, I went over it with Sikaflex, which is a black silacone-like substance. It takes a while to cure but once it does it sticks for a long time. Here is a close-up of the glued together areas as a reference:

You can use what ever you want to stick it together and I’m sure there are many easier and better substances that would do the job, but this worked for me and looks good.

Once the glue has fully dried, just refit the surround which while it’s off you could paint or you could wrap it like I did with mine in carbon. If the RS6 grill didnt come with the audi rings, your old ones from your A4/S4 should fit on (mine did).

Whilst you have the bumper off you may need to spray the bumper beam/crash bar going across behind the grille, otherwise it will stick out and not look as nice.
