Can someone please post pics of the NBS stock intake? I can't seem to see what's going on way down there without pulling it out, and so many here have a CAI I thought maybe you'd have the old one lurking in the garage. Hopefully someone has an '06 (or whatever is similar.)

Thanks in advance!

Don't TELL me you threw them out!
I just need to see how deep that damn muffler goes. Can it be cut off? Patched up on the hole?

what is this so called "muffler"?

99sleeper, i noticed that you have a TB spacer, did that do anything for your truck? i have a 2000 sierra.

I also have one on my Suburban, I dont know if it added any power, but it feels like it sort of "shifted" the power curve. Oh, and it makes this whistling sound that makes people keep asking me do I have a turbo.

It's a big fat box of molded plastic that hangs down below the inlet tube, past the airbox. What I want to know is if the sucker is passive, or if incoming air is "rerouted" through that thing via molded air ducts. If that is the case, I'm putting on a CAI (or an airaid tube) just to have the incoming air go straight to the TB.

Am I making sense? :cool:

I should be installing a FRAM Boost Intake this weekend so I'll grab my g/f's digital camera and snap some pics for you if you still need them

tbspacer- small power gain and cool wistle

intake muffler- the air goes in there and gets silenced when i removed mine it sounded better and performed better

There's no power gain with a spacer on a dry manifold...the whistle is rice-ish to me

so the "muffler" is the part of the intake tubing that is hanging down? how did you guys remove it, cut it off and patch the hole up? what is the point, so the intake is quieter?

This is the 'muffler' you're talking about. In the OEM case it's to reduce the sound of the air intake.

On my outlaw it's different looking for a different purpose (supposedly to create a boost in air around 3k rpm).

good luck.
