Sure don't buddy, but it looks greyish, like if it was dirty; took the plenum out when car had 1.5K miles, so it wasn't dirty from use. It's not black, like one might assume. The layer is probably sandwiched, for what I could tell.
I wouldn't put a crappy 'racing' filter even if I was paid for it, especially in this dusty area. Definitely not worth inhaling dirt to gain a HP or two at the very top of the rev band, which I rarely reach anyway. The european stock filter sold by AA (for my '08) is relatively cheap at $50. Wish I could split it with somebody else since I have to buy 2; don't know if I'll keep the car after warranty at this point. Take care.
