I've been using this BPV for the last 15k miles with zero issues. I used it on a Perrin TMIC and then with my AVO FMIC. Never leaked, and held pressure up to 26psi. I won't be able to use this with my new setup, so it is up for sale.
It comes with everything shown in the pictures, which is everything it came with when I bought it. I was using the blue (stiffer) spring, but swapped it back out for the yellow spring for the next owner, which is best suited for a TMIC. The BPV can be rotated for a perfect fit. The o-ring style gasket will NOT work with the OEM TMIC, as the diamond shaped BPV opening goes beyond the o-ring. I would clean it up and grease the piston if needed about every two months. It made a nice high-pitched "chirp" between shifts with my 83mm intake and blue spring at 24psi.
This is the only video I have that you can somewhat hear the sound between shifts:
