Has it got a p/n on it? If it does Google it up and see if it's one of the dry ones or not.

 

I would clean it and Oil it , and see how it looked .

 

It is either black, which seems unlikely to me, or darned filthy! In that case clean it in your favourite degreaser and check what you have. If it looks a bit pink then it is definitely oiled, as that is the colour of K&N filter oil. If it is white/grey it may still be a K&N, but has never been oiled!!!!

 

I have basically the same filter in my '00 RK, I think it came as part of the Stage 1 kit the previous owner installed. Anyway, yes it's a K&N that should be oiled. In my experience over time that red dye fades so that it doesn't appear to be oiled, my guess is the reason yours looks like a grayish color. Mine looks exactly the same right now. Also, your filter is maybe a little bit dirty but not much, you can see all of the black screen. Per the K&N website, you don't need to clean it until there are spots where you can't see the screen. Remember, a partially dirty filter is actually more efficient that a perfectly clean one. Hard to resist the temptation to clean it when it's not all pretty, but that's the fact. FWIW my filter looks VERY similar to yours, has 18k since the last cleaning, I'm feeling the urge to clean it because it lost that pink color, but from everything I've read the science says it's fine until you have serious layer of crud on it.
