Uhh, that's your MAF. You need that. You'll need to buy a piping kit that can adapt the factory MAF. I'm assuming you have a NT, which would rule out the need for a GM MAFT, so you're pretty much stuck, uless you can weld. If so, i'd say make an aluminum adaptor plate, or just buy a kit such as the k&n, which gives you an open filter element that covers the MAF, From there, you'l just need an appropriatly sized coupler, and you shouyld be fine.
