Not to argue but I'd like to see how the 05 is different than the 06 or 07 if the truck is still a GEN 3 NBS style. If the knock sensors are still up top like the 06-07 NBS trucks are the manifolds are the same as the older ones.

TBSS and NBSS are the same intakes, the silverado/sierra/yukon/tahoe/suburban didn't get the NNBS intake until the body change in 2007.5. As you said won't fit and I understand that.
