Nope, you have a DV on your car right now. It's just stock vs. an upgraded part that holds boost "better and longer". A CAI will make a similar sound, however not identical to a BOV. My HKS SSQ is unmistakeable.
I'd recommend keeping your diverter valve or upgrading to an aftermarket one rather than a BOV. The diverter will "blow-off" excess boost like the BOV but rather than blowing it off straight inot the atmosphere, it is recycled so your car can determine how much boost is blown off and adjust accordingly. A DV rather than A BOV should increase the life of your turbo.
