Yes, but be aware that there are lots of fake parts or rejects as well. The easiest thing is to make the genuine box, so they appear to be genuine.

Not so long time ago, I've bought a 6 pack of Mann oil filters for VAG cars from a reputable ebay seller (UK) for $72 and they were fakes. From then I buy only genuine from the local suppliers, because it's not worth to save a few dollars per item.
