T1 2.7 Aftermarket k&n or airaid intake tube questions

[Flak_Jacket]

I have tried to search for this but haven't succeeded. I just got a 2023 2.7 GMC Sierra. I am trying to find out information about the aftermarket filter replacement and intake tube. Not the $500 entire airbox replacement. Either the K&N or airaid specifically. I just want to know if anyone has installed them and what was the outcome. I have seen some install videos on youtube but they don't review after the install. I am not expecting a boost in HP even though airaid claims 10hp, but i am looking for information about the sound and if it gains any MPGs. 

 

Does the turbo make more turbo noises? Does the 4 cylinder make the stupid "groning" noise more often or louder than it already does? Any increase in MPG? Do you have any pictures of the inside of the old airbox you could post? It's a huge rectangle box and would like to know if there are baffles inside to reduce sound? Any additional things you noticed that i might consider before buying?

 

Thanks in advance.
