Port behind Air Filter
Hi guys Im a newb here with an 06 chevy silverado with the 4.8. I bought the truck non running as a project, and it came with what I was told was an ls1 intake manifold. My question today is (there will probly be many more questions to come), there is an round opening on the front of the manifold, on the top, behind where the air filter attaches. Looks like it needs some type of cover or something. This is the only pic I have at the moment.

Plugging that hole would be bypassing the egr. You would also need to plug the port in the exhaust and have a tuner turn it off in the computer so you don't get a check engine light

The pcm will be the determining factor. If its the pcm that came with the motor its completely possible to keep the egr you just need the rest of the parts for the system. Egr valve, egr tube, assorted gaskets and fasteners
Oh and there is not a sensor that goes in that hole its a metal pipe
