Air box question

[Jobi-Wan Kenobi]

I noticed the other day that my air box lid has a broken tab for one of the screws. I'm not sure what the assembly code is for it but its not the high capacity K47 option. I called a couple local salvage yards seeing if they would have one and no one did. But one place did have the K47 assembly in stock. Anyone know if this is a direct swap? Is even a worthwhile change?

I've never heard of that rpo. What makes it different/better then the standard airbox?

@Tonyrodz never heard of it myself until yesterday.

Kind of odd that the same part number appears to fit different engines, with some overlap between engine codes (searched a 2003 Tahoe RWD):

High capacity k47 vs non ??

I'm confused. I thought anything 98+ had the round air cleaner and older had the square but the ***** says they have an air cleaner from a 98 burb 6.5TD but it's not a k47 ? could they be confused or am I ?:???:

Maybe it's the one with that little doodads that tells you if it's clogged.

He tells us right away that the only difference is the filter itself; the box is the same.

I may just go and pick that one up and see if it fits.

All K47 means is that the car takes a high capacity air filter. It is twice as thick and fits into the same airbox.

I have trucks with and without K47 and all run the same high capacity air filter, A3085C.

Double check for yours, I have GMT900s.

Missed that.

So I stopped and picked up the air box tonight. The bottom pieces are identical, but someone did remove the tube thing from inside of mine. The cover does have a restriction indicator.

Replacement and the original.
