I have the Mountune BPV. It is superior quality over stock, and on par if not better than any other aftermarket BPV for our car. It's a direct swap, no tuning adjustments required. If you are not specifically looking for the sound that a BOV provides it's a no brainer imo.
Next I would say Boomba now makes a BPV along with their popular BOV. I like Boomba products and they have great customer service.
Those would be at the top of my list. I didn't want to vent to the atmosphere so it was between the Mountune and the Boomba BPV for me. Quality of workmanship would be a win either way. I chose Mountune for 3 reasons, it resembles the stock valve in size and shape, so since I'm still under warranty and stock but that and tune I wanted to fly under the radar a little more if I had to go in for a warranty issue, I was hoping they would over look that, opposed to having a different designed piece that was anodized and in your face more, second it was slightly quicker/easier to install, you have to modify the solenoid bracket for the Boomba (talking like a 5 minute difference with good tin snips, it's a stretch I know but, I honestly thought about this), and without a group buy on the Boomba Mountune is cheaper.
