You could probably handle the install. I'm saying that as someone who never modded a car until my FiST.
I installed a GFB DV+, and that is in the exact same location you would be installing the BOV. The only real difficulty is reaching the location with an allen key to remove the bolts from the stock DV and then tightening the bolts of the new BOV.
Here is a video of the install.

I've noticed CJPonyParts always goes underneath to reach the DV location (they have a lift - must be nice). You could do the same if you jack up the car high enough. But for me and many, jack up the passenger side, remove the wheel and get to it from the wheel well.
If you search on the forum for GFB DV+ install, you should get a ton of different techniques to reaching that area. For me, it came down to a stubby little ratchet for a couple bolts and a super long extension and swivel head for another.
I'd help but I live on the wrong coast. I used to live in Oceanside years ago!
