Since I haven't seen the GM intake of it's like others its a K&N. In that case get the MPFab
The GM Performance Air Intake may be my next upgrade. Iamgmparts.com
sells it for around $450.00. Best part about it is that it will not jeopardize the GM powertrain warranty if the dealer installs it.
There is a code that the dealer uses to recalibrate the ECU, which is a mild tune.

No intake you install will jeopardize your PW unless it was the cause of the failure. IMO it's a waste of money. You'll get more for the money if you go somewhere else

We should remember preserving warranty is important to many and the GM intake seems to include a tune as well as the intake. A mild tune, I would guess, but a tune.

a whole used engine can be had for around $600-700. ive already spent plenty more than that in performance mods. why not save the $200 from the GM intake and put it towards other mods?

Keep in mind most published pricing includes installation of the intake and "authorization code". If you price this intake through a dealer you'll get the same price as online retailers, no shipping, and installation included. Something worth considering since the GM part is well designed and won't void the B2B warranty since they designed the intake and ecu coding

I was looking into this and was wondering what the authorization code does. Also would installing another intake (i.e. K&N, Mpfab, etc.) yourself throw any codes?

The ecu is programmed to keep the fuel and air trims in factory spec. The aith code allows the ecu to grant a little more fuel for the additional air flow, so potentially more power. No one has put it on the dyno as far as I've seen and GM doesn't really claim any hp figures.
No one seems to have code issues with intakes, but seems most everyone that gets one goes tune shortly after since the factory intake really isn't that restrictive. An intake alone is not a big power boost no matter what brand you use. In conjunction with a tune (and exhaust changes) it becomes a factor

So the code is pointless if you are planning on tuning with Trifecta or similar tunes?
For the 1.4L Sonic, Chevrolet Performance offers a cold-air intake and cat-back exhaust system. Both upgrade packages come with dealer-installed ECU calibration. You can have either or both, and GM will tune your ECU accordingly.
Insider info (I'm a Parts Manager for a Chevrolet dealership):
The ECU calibration does two things. First it flashes a mild fuel re-map to the ECU to allow extra fuel flow under high engine load and throttle settings to maintain proper air/fuel ratios and emissions. The fuel re-map is matched to your car's intake and/or exhaust upgrades through Chevrolet Performance. The second thing the calibration does is extend the timing for the turbo. It doesn't introduce extra boost (stock the car can produce up to 20psi), but it does cause the turbo to kick in at lower RPM.
On a personal note, I have installed both the Chevy exhaust and intake packages with tune. There is a noticeable difference in low to mid torque, and much more aggressive sound, and better mpg (before I put on wider tires I was getting up to 49mpg on the highway). Granted the Chevy tune isn't going to be nearly as potent as the aftermarket offers, but it's rock solid, warranty-friendly, GM approved, and you don't have to use any special fuel. GM estimates a 10 hp & 15 ft/lb increase with the exhaust package. Speaking with a Chevy Performance expert, I was told to expect similar gains with the intake w/tune. The two together should net about a 15 hp gain.

Oh, and don't forget to pay attention to your clutch. According to GM, either the air intake upgrade or the exhaust upgrade will require an upgraded clutch if your Sonic was built prior to 2014. It may not seem necessary at first, but after a while the extra torque will cause slippage. After just a few months I did notice that the friction point was getting a bit more numb than usual.

What if you go with a Borla cat back. Do you still need a tune? Also if the dealer installs the cat back do they still run the tune.

That is correct if your only objective is sound.
it's not the size, it's how you drive it....
