The blackwing filter is an order part from SLPonline.
You may want to think about keeping the paper filter on, I switched back to paper after the recharging kit coated my MAF with that oil. Plus the reason those filters flow better is because the filter holes are much bigger hence allow more dirt to easily pass into the combustion chamber. Combined with the slow drip flow of oil from the PCV you can clog up your intake with a layer or oil and dirt (over a long time tho). Ill be taking off my PCV system once I have the time and putting on some breathers instead.
