Question Cold Air Intake

Does anyone have any recommendations on Cold Air Intakes? I'm currently looking into purchasing in the MST CAI but before I went ahead, wanted to see if:
1) Does anyone have it? How do you like it? How does the sound of the car change? Any noticeable performance changes?
2) If not MST, what other CAI would you recommend getting?

TIA!

I installed this MST intake on my mom's C300 and I definitely recommend it. I don't have any pics currently, but it looks like it does on the website. Shipment was extremely quick from Taiwan. Packaging and quality are great for the cost. Install was very easy and fitment is on point.
Only 2 deviations from the instructions:
  1. There was one wire that was attached to the factory airbox, I just had to loop it and zip tie it to the MST airbox. This wasn't difficult or any issue, and may not apply to all cars. It wasn't in the instructions or the one install video I found on YouTube, but my car is a 2018 convertible with the 9spd, so maybe it's not on earlier 7spd sedans.
  2. I didn't like the MAF wire running kind of loose through a hole in the MST box, so I grabbed a grommet from my toolbox and threw it on. Not required or visible or even needed, but I preferred it.
Intake and turbo noise is definitely more noticeable but not excessive; maybe increased by 20%, sounds a little racier under load. I also noticed a little more DI injector clatter at idle, but not bad. I think we can all agree the M274 isn't the most refined or pretty sounding motor, so this isn't an issue.

I didn't really feel any more power on the butt-dyno, so it may not be "worth it" for some people. But if you're doing a CAI for the usual reasons of some increased sound, increased underhood appeal, and just to wrench on your car a bit, go for it. It's a quality piece at a great price.

Thanks for the detailed input @Silver!! More and more, I want to pull the trigger and but it. I'm debating between getting the CIA or the 10.25 Android screen upgrade for this month.

If you do have any pics, please do share!
