I wonder if either one of those is attached to the engine. I am not a fan of non-functional parts on cars. That being said, I did inherit a cowl induction hood from the PO and it is not functioning in that capacity. It does however, let hot air out of the engine bay. I was going to try and incorporate it with the intake when I put the LS in, but the plumbing and logistics just wasn't worth it. Maybe I will find a clean unmolested hood some day.
