I know a guy who has a brand new (100 miles old) 93 Cobra upper/lower intake that has been ported and polished with a upper to lower plenum spacer. He's selling it for $200 with only a lower gasket (no upper gasket). This sounds like a good deal, but is there anything I should ask him about? Will this work on my 94, or will I need that adapter? Need info fast, I might wanna get this next monday. Thanks
