Is your current setup: pod -> AFM -> standard intake pipe?
If so, yeah you just need the airbox and snorkel with a new filter. The afm will bolt into the bottom of the airbox, it's all fairly straightforward.
It will run fine, you could check it on a dyno if you really wanted to. FWIW I'm running 280rwkw with standard airbox, so they aren't as restrictive as some people think
