Does this have a diagram? I'm asking because the box has t end hoses; I don' have any idea why is the other one for. can anybody send me a link to sew

the 2 ports are for the Crank Case Breather hoses. you will have to go to the AFE website and look up the installation guide.

Did you leave in or remove the rubber plug for the auxiliary air inlet? If so, why?

If you put it in it will cut down on the under the hood noise. I have ran it both ways. I just keep it in my center console when it's not in.

Those this fit on a 2017 gmc sierra denali?

Yes it does. Have it on my 18 Denali and same layout.

No idea, but check with aFe if they have a CARB # for it. Only legit way to be CA legal.

Good air.

Sounds normal when cruising around or on the highway, but when you get on it you can hear the air box kicking in and the volume goes up. Not alot but you will hear it even with the stereo on. Easy install. Took more time to take the old stuff out than putting the new box in. 2017 GMC Sierra SLT 6.2lt.
