IMO, you wouldn't be upgrading. There is no aftermarket CAI that can out filter or even come close to the stock filter. There is also no significant HP gain.
The only gain would be ease of replacing the CAI filter.
If you think you'll be saving money in the long run with the price of stock filters, you might what to reconsider. Without good filtration, over time, you'll end up dusting the turbo. IIRC, the compressor wheel spins somewhere around 30k rpm, the dust particles that get past the filter will make the fins look like they have been sandblasted.
There are those who complain about how it's a P.I.T.A to replace the stock filter, I didn't find it that hard to do.
When I come across a stock unit that's free/cheap, I'm going back to.
