I have heard from owners that the AFE Stage 2 works pretty well. We have one in stock that was bought for a 2013 but we found out that it won't work on a 2013.

you won't notice any difference on a stock truck, just so you know before you purchase. the stock filtration setup is very efficient and good at its job

I heard the LML isn't the same as the LBZ/LMM intake, may not be accurate.

Another can of worms here....

I'm running S&B on all three of my duramax trucks, and love them.

I know they changed some more stuff for emissions purposes. Have a family friend with a denali who installed the AFE unit and we couldn't tell a difference after driving before and after.
