    Would a replacement '07 NNBS intake and Throttle body be what I'm looking for for more power on my '03 Yukon 5.3L?

    I've heard this is good for a power increase. I see AC Delco OEM replacement units on Rock Auto for a decent price. Is that the right parts?
    Looks like #2172422 Throttle Body and # 12580420 on the intake.

    Are the intake gaskets the same between the 2?

    I know some have done the TBSS intake & TB swap, but many have had computer/code issues. IIRC, the NNBS intake & TB was the way to go.

    Any info/details here about parts or any relearn procedures would be a big help-
    I do have a BBP Autocal ready to get to work when headers, exhaust and intake are done...

    Thanks!

    Will the newer TB bolt up or would I have to change the TB linkage/cable set-up to something different than it has now?

    Was hoping that would be a straight swap...

    Newer throttle body is a six wire, I'm pretty sure yours will be an eight wire TB plug. You can get an 07 up intake (basically a TBSS intake with a four bolt throttle body) and just get an adapter plate for a three bolt 87mm throttle body. That'd be plug n play, although you'll then need a tune.

    Any updates on this intake being installed on a 5.3L?

    My research only turned up conflicting part #'s and confusion as to a clear path. I gave up...
