Q1: No...There are no stickers with the Intake Manifold, but have them for the K&N and Headers...I'll even throw in some Summit Racing 35th Anniversary ones
Q2:Yes...This is a a stock replacement filter, not Cold Air (then I would be charging $300 or more
)
Qs3-6: Yes the intake and headers are emissions legal and require no other modifications-they both bolt right in...all you need is a new intake gasket when the swap is made, and the headers are not coated-they are painted.
Here are some links to what I have on SummitRacing.com
