Will this fit on a 03 gmc envoy with the 4.2 in it?

Probably not, most likely you have to have the right length of tube and the rubber hoses to connect everything,I would type in the search 03 gmc envoy 4.2L coldair intake and see what comes up, hope that helps.

Fit a 2500dh 6.6 duramax?

Not for the diesel applications

Anybody know the k&n replacement filter number for 2003 silverado 5.3??

I know S&B filters KF-1000 & KF-1042 fits straight to MAF

I would like a second filter so when i clean one i can put the other in and go? where do i get one

I would definitely upgrade the filter, these ate cheap and aren't meant to be cleaned. If you measure the inlet hole you can find this filter for any brand.
