No, I didn't get the BPV. 2 reason: 1) there's really not a good spot for it and 2)I've heard that it doesn't help from preventing hydrolock UNLESS you submerge the entire filter under water. And I don't plan on driving into any lakes. That's just what I've heard, so I really don't know if that's true. In the meantime, I'm just a lot more careful where and how I drive whenever it rains.
