Mystery part

[boostx2]

Does this belong on a B8 S4, and if so, where?

(For scale, it's probably 10" wide)



Had the front bumper cover/carrier off today for an EPL stage 2 upgrade. This part was basically laying inside the bumper cover on the driver's side, near the bottom. For the life of me, I can't see where/why it would fit somewhere nearby.

Went back together without it, but extra parts are rarely a good thing.

2nd owner, no previous mods or major service that I know about but a few other little things make me think someone has had the front clip off before...

That goes inside the fender liner

Sure, that's where it would have to come from. Can you be more specific? I see no attachment tabs or obvious clip locations. The shape/curve didn't seem to match anything in there either.

It's directly behind the side intercooler, glued on the fender Liner.
I guess someone pulled the liner too far back and it separated.. Maybe has something to do with airflow from the smic

I saw this when I had my front bumper off. I was really tempted to take an art knife to the honeycombs and open those holes up to allow better air flow through radiator beside the wheel well. I cant' see it getting good airflow...

I've thought of this when I had the stock FMIC, cutting the trim and adding a vent on the liner like the 911s didn't seem like a bad idea.
I guess Audi has its own reasons for keeping it shut so I just got the upgrade.

They're open on some of the RS models (maybe all? Haven't looked...)

If the aux rad was right up against the liner I would, but its not. The lines and supercharger coolant pump are there and the tires would kick up a tone of road crap with no where to go.

Amz looks like it's all FI RS.

Covering whatever that can be corroded and setting the fins at a certain angle can reduce the gunk going in but trying to make a custom vent has a huge fail potential lol.
