I was cleaning out my air box today and noticed that the foam seals are getting a little brittle. I guess so since they're 7 years old. These would be the strips that go in between the two halves of the box, plus the big round one that goes up against the inner fender well. I'm assuming they're peel and stick.

Are these available through GM Parts? If so, would anyone by chance have a part number?

My parts breakdown doesn't show it seperately.

:home depot:

I agree with Bill on this one. Unless you absolutely must have OEM, all you need to do is control where you air flow comes from, outside or underhood. There are plenty of peel and stick weatherstripping products available at the local hardware store.
