Yes they will. FYI, they're the exact same side skirts found on the A5 S-line's exterior body treatment (in those countries where it's available).
The actual part description in Audi's system is called "stone guard". The stone guards are attached to the body of the car using 9 clips on each side. An alternative to attaching the stone guards using the clips (which I assume would necessitate drilling holes into the body) is to use a very strong bonding agent. Body shops sometimes use this to attach spoilers to trunk lids.
Just give your dealership's Parts department a call and they should be able to order those "stone guards" for you.
the side skirts dont look right to me, they stick out way too much, can just instantly see its some pointless peice of plastic. i think it spoils the lines of the car. UK a5 sport model just look so much more sleek than the a5 with sline. And lol at those spoilers on tyresmoke, not feeling them what so ever.
Billy The Fish,
I've fitted side skirts to my car & they really look good, contray to some other opinions posted ealier, they cost around £80.00 ea plus painting & fitting so probably around £300.00 all in. I also put a S5 front & rear on my car I just loved the look of the S5 but not the running costs. the car definatly benefits from these after sales additions (retro fit) Ithink I might join a few of the other guy's by having my car lowered & definatly wheel spacers fitted .
If you'd like part numbers & any other info please dont hesitate to ask !
