Resolved Mystery Throttle body?

[JoshMc]

Okay so this throttle body randomly appeared on my back pourch, don't even remember getting it, but I have a question as to what it came on? It's much different than the one on my 2g, and the opening is larger, if anyone could help me out that'd be awesome, and if I can even use it on my 2g build!

Here's some pics
