You'll have to make sure the rails injector holes line up with the injector holes on the lower intake too.
I don't know if Mike makes a set to be a direct bolt on to the stock lower intake.. If he does, and assures you they will fit then forget what I said above.
they are machine polished then bright anodized not powdercoated And if i can recall this order (cause i think it only happened once), everything else including the fittings were to be black, so i figured a free matching upgrade wouldn't be such a bad thing.. true?
